I suppose 17x^ means 17x².
and that we must solve the equation.
Step-by-step explanation:
[tex](x-3)(x-5)-(4x+1)(1-4x)=14x^2\\\\x^2-3x-5x+15+(4x+1)(4x-1)=17x^2\\\\x^2-8x+15+16x^2-1=17x^2\\\\-8x+14=0\\\\8x=14\\\\x=\dfrac{7}{4} \\\\\boxed{Sol=\{\dfrac{7}{4} \}}\\[/tex]

It was recommended that students drink 48 or more ounces of water.
How could you use a histogram to easily display the number of students
who drank the recommended amount?
Histograms are used to graph the frequency of data, where the length of the bar represents the frequency.
The number of students that drank the recommended amount of water are 125
Given that
[tex]Recommended = 40\ or\ more[/tex]
The number of students who drank the recommended amount are students whose frequency (i.e. length of bars) is 40 or more
From the histogram (see attachment), only 2 bars are above the frequency of 40.
And the number of students in these bars are: 50 and 75
[tex]Total =50 + 75[/tex]
[tex]Total =125[/tex]
Hence, the number of students that drank the recommended amount of water are 125

A circle is cut from a square piece of cloth, as shown: A square, one side labeled as 34 inches, has a circle inside it. The circle touches all the sides of the square. The portion of the square outside the circle is shaded. How many square inches of cloth are cut from the square? (π = 3.14)
Answer: 907.9 in^2
Step-by-step explanation:
The square has sides of 34 inches each. A circle drawn in the center and touching the edges would have a diamenter of 34 inches, and thus a radius of (34/2) = 17 inches. The area of a circle is pi*r^2. Area = 3.14*(17)^2.
Area of the circle = 907.9 in^2 That is the material cut from the square.

#14 please geometry hw
Answer:
7/18
Step-by-step explanation:
Area of ABED = 49
Side lengths are 7, its a square
Since AD = 7, and AG = 9, DG = 2
DE = 7 and 2 x 7 = 14
14 is the area of the small blue region.
AC = 10, and AB = 7, so BC = 3
CF = BE = 7
3 x 7 = 21
21 is the area of the big blue region.
21 + 14 = 35
Area of the whole shape is 9 * 10 = 90
35/90 = 7/18

Answer:
x° = 43°x° = 51°x° = 86°Step-by-step explanation:
Given,
x + ( x + 8) + 2x = 180° [Since angle sum property of triangle]
=> x + x + 8 + 2x = 180
=> 4x + 8 = 180
=> 4x = 180 - 8
=> 4x = 172
[tex] = > x = \frac{172}{4} [/tex]
=> x = 43
As,
We got value of x as 43 so,
x° = 43°
x° = 43 + 8 = 51°
x° = 2 × 43 = 86°

Which expression is equivalent to -9a – 10 – 6a + 7?
Answer: a = - 1/5 or a = -0.2
Step-by-step explanation:
-9a – 10 – 6a + 7 = 0
>> -9a-6a = 10-7
>> -15a = 3
>> -15a/ - 15 =3 / - 15 ( divide by -15 both side)
>> a = - 1/5 or -0.2

9/5-(-6/10= reduced to the simplest form
Answer:
Since it is a double negative, you add the two together. First, you must find the LCD though. Which is 10. So you multiply the left side by 2. This comes out to 18/10 - (-6/10) but since there's two negatives, you add them, so it's 18/10 + 6/10 = 24/10 = 12/5
Step-by-step explanation:
The answer is 12/5 (top is explaining how I got there.)
Answer:
12/5
Step-by-step explanation:
9/5 - (-6/10)
Subtracting a negative is like adding
9/5 + 6/10
Simplify 6/10 by dividing the top and bottom by 2
9/5 + 3/5
12/5
