Multiply 4√2 x 6 √18
Answer:144
Step-by-step explanation:
Solve. x-6=-18
A x=-24
B x=-12
C x= 12
D x= 6
x - 6 = -18
x = -18 + 6
x = -12 ← the end
Answer: B)
[tex]\boxed{\underline{\bf \: ANSWER}}[/tex]
[tex] \sf \: x - 6 = - 18 [/tex]
Add 6 to both sides.
[tex] \sf \: x=-18+6 [/tex]
Add -18 and 6 to get -12.
[tex] \boxed{\underline{ \bf \: x=-12 }}[/tex]
=> The correct answer will be Option B - x = - 12

Answer:
Step-by-step explanation:
Set up equation
[tex]\frac{5x}{3} +\frac{3x-2}{6} =2-3x[/tex]
Make 5x/3 and 2-3x have a denominator of 6. To do this, we multiply everything in 5x/3 by 2 and multiply everything in 2-3x by 6.
[tex]\frac{10x}{6} +\frac{3x-2}{6} =\frac{12-18x}{6}[/tex]
Add the Left fractions numerators and set them equal to the Left side.
13x-2=12-18x
13x=14-18x
31x=14

Answer:
w = -8Step-by-step explanation:
Given:
3w + 6w - 19 = -91Isolate w, add 19 to both sides:
3w + 6w = -91 + 19Simplify both sides:
9w = -72Divide both sides by 9:

Which of the following points lies on the line defined by y = -3x – 7?
A. (2, -1)
B.(-2, 1)
C. (-2,-1)
D. (1,8)
E. (2, 1)
=========================================================
Explanation:
If we tried the x coordinate of choice A, then,
y = -3x-7
y = -3*2-7
y = -6-7
y = -13
This shows that the point (2,-13) is on the line and not (2,-1). This rules out choice A, and also choice E.
Let's try x = -2
y = -3x-7
y = -3*(-2)-7
y = 6-7
y = -1
This shows that (-2,-1) is a point on the line, and it points us to choice C being the final answer. This rules out choice B.
If we tried x = 1, then,
y = -3x-7
y = -3*1-7
y = -3-7
y = -10
Which shows that (1,-10) is a point on this line, which rules out choice D.
The visual summary is shown below as a graph. Only point C is on the red line.

please help I’m pretty sure the answers are right I just need a reasoning for my answer like a paragraph of my explanation.
Step-by-step explanation:
All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side;a+b > c
a+c > b
b+c > a
If this is true for all three combinations of added side lengths, then you will have a triangle.A)triangle is possible with these measurements
2+3 >4
2+4> 3
3+4>2
B)triangle is not possible with these measurements
2+3 >6
2+6> 3
3+6>2
C)triangle is possible with these measurements
90+45+45=180 degrees(sum of interior angles of a triangle is 180 degrees)
180=180
D)triangle is not possible with these measurements
90+60+60=180(sum of interior angles of a triangle is 180 degrees)
90+120 =210 degrees
sum of interior angles of the triangle is more than 180 degrees
Therefore it is not a triangle

7. Choose the correct answer. If there is direct variation and y= 27 when t= 4, find y when = 12.
a. 9
b. 0.56
c. 81
d. 1.78
Answer:
c
Step-by-step explanation:
Given direct variation between y and t , then the equation relating them is
y = kt ← k is the constant of variation
To find k use the condition y = 27 when t = 4 , then
27 = 4k ( divide both sides by 4 )
6.75 = k
y = 6.75t ← equation of variation
When t = 12 , then
y = 6.75 × 12 = 81

Find the slope of the line that passes through the points (0,-11) and (8,-8).
To find the slope of a line, we can use the following formula:
[tex] \displaystyle \large{m = \frac{y_2 - y_1}{x_2 - x_1} }[/tex]
m-term stands for slope or gradient. The formula is useful whenever you want to find a slope of two points.
Let these be the following:
[tex] \displaystyle \large{(x_1,y_1) = (0, - 11)} \\ \displaystyle \large{(x_2,y_2) = (8, - 8)}[/tex]
Substitute the points in formula:
[tex] \displaystyle \large{m = \frac{ - 8 -( - 11)}{ 8 - 0} }[/tex]
Negative multiply negative always come out as positive.
[tex] \displaystyle \large{m = \frac{ - 8 + 11}{ 8 - 0} } \\ \displaystyle \large{m = \frac{ 3}{ 8 } } \\ [/tex]
Since m stands for slope, we can say that:
[tex] \displaystyle \large \boxed{ \tt{slope = \frac{3}{8} }}[/tex]
Answer:
Step-by-step explanation:
(x₁ ,y₁) = (0,-11) & (x₂ , y₂) = (8,-8)
Slope = [tex]\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]=\dfrac{-8-[-11]}{8-0}\\\\=\dfrac{-8+11}{8}\\\\=\dfrac{3}{8}[/tex]
The length of a sandbox is three feet longer than its width. Write the expression that would represent the perimeter of the sandbox.
Answer:
4w + 6
Step-by-step explanation:
Let width = w
Length = w + 3
Perimeter = 2*length + 2* width
= 2(w +3) + 2w {Use distributive property}
= 2w + 2*3 + 2w
= 2w + 6 + 2w {Combine like terms}
= 4w + 6

A rectangular block has square base of area 64 cm². If the thickness of the block is 5 cm, find its total surface area.
Answer:
total surface area of cube is 6 * area of one side
therefore area of one side is given 64cm^2
thickness is also given 5cm .
TSA is 64*5 = 320cm^2
hope it is helpful
Answer:
288 cm²
Step-by-step explanation:
The square base has an area of 64 cm².
That means the sides of the square base measure 8 cm.
The perimeter of the base is P = 4 * 8 cm = 32 cm.
The lateral area is Ph = 32 cm * 5 cm = 160 cm².
The two bases are congruent, and their combined area is 2 * 64 cm² = 128 cm².
The total surface area equals the sum of the lateral area and the area of the bases.
SA = 160 cm² + 128 cm²
SA = 288 cm²

Hi
Your question would be better with " Could you help me please ? " at the end. Quite sure your mum told you that some time in the past.
I will show you how to solve but you will do the calculus. Math is all about rules, methods and training. If you dont practice, you will never progress.
rule : you must know by heart your remarkable identities.
Here we have : ( 4x-3)² - (2x+5)² = 0
It 's of the form A² -B² = ( A+B) ( A-B)
here A is : 4x-3 and B is 2x+5
Now let's apply rule : ( 4x-3)² - (2x+5)² = ( (4x-3) +( 2x+5) ) ( (4x-3) - (2x+5)
= ( 4x-3 +2x+5 ) ( 4x-3 -2x-5 )
= ( 6x +2) ( 2x-8)
so : ( 4x-3)² - (2x+5)² = ( 6x +2) ( 2x-8)
so ( 4x-3)² - (2x+5)² = 0 means : ( 6x +2) ( 2x-8) = 0
Rule A*B = 0 if A = 0 or B = 0
A is 6x+2 and B = 2x-8
So I let you now work :
You have to solve : 6x+2 = 0
and 2x-8 = 0
Solutions of this two calculus will be the solutions of ( 4x-3)² - (2x+5)² = 0

The piecewise defined function f(x) is graphed below. What is the value of f(2)?
f(2) = –2
f(2) = –1
f(2) = 4
f(2) is undefined
Answer:
f(2) = -1
Step-by-step explanation:
Looking at the graph, there appears to be two points at x = 2. However, looking more closely, we see that the point (2, 4) is empty; this means the graph goes up to this point but does not hit this point.
The point (2, -1) is filled in; this means the graph hits this point.
Step-by-step explanation:
The value of f(2) on the graph of the piecewise function is -1
How to determine the value of f(2)?From the graph of the piecewise function, we have the following highlights
When x = 2, the function has corresponding values at y = 4 and y = -1
However, the graph has an open circle at y = 4 and a closed circle at y = -1
Closed circles show inclusiveness
This means that the actual value of f(2) on the graph is -1
Hence, the value of f(2) on the graph of the piecewise function is -1
