Answer:
1) (f+g ) x = (x²-4)+ (x+2) = x²+ x –2
2) (f - g ) x = (x²-4) – (x+2) = (x²-4)+ ( -x - 2) = x²–x–6
3) (f × g ) x = (x²-4)(x+2) = x³+2x²– 4x – 8
4) (f / g) x = (x²-4) / (x+2) = x – 2
5) ( f + g ) 4 = (x²-4)+ (x+2) = ((4²)-4)+ (4+2) = ( 16–4) + (6) = 12+6 = 18

What is the product 1.3(-3.1)(4.2)
Answers
Explanation:
-3.1 x 4.2
= -13.02
-13.02 x 1.3
= -16.926
The value of product will be;
⇒ 16.926
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The expression is,
⇒ 1.3 (- 3.1) (4.2)
Now,
Since, The expression is,
⇒ 1.3 (- 3.1) (4.2)
After product, we get;
⇒ 1.3 × (- 3.1) × (4.2)
⇒ 4.03 × 4.2
⇒ 16.926
Thus, The value is = 16.926

-(7-4x)=9
can somebody help me with this, and if you could, can you show work?
Answers
Answer:
x=4
Step-by-step explanation:
Simplifying
-1(7 + -4x) = 9
(7 * -1 + -4x * -1) = 9
(-7 + 4x) = 9
Solving
-7 + 4x = 9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '7' to each side of the equation.
-7 + 7 + 4x = 9 + 7
Combine like terms: -7 + 7 = 0
0 + 4x = 9 + 7
4x = 9 + 7
Combine like terms: 9 + 7 = 16
4x = 16
Divide each side by '4'.
x = 4
Answer:
x = 4
Step-by-step explanation:
-(7 - 4x) = 9 (Given)
-7 + 4x = 9 (Distributed)
-7 + 4x + 7 = 9 + 7 (Add 7 on both sides)
4x = 16 (Simplify)
4x/4 = 16/4 (Divide 4 on both sides)
x = 4 (Simplify)
Devon is 2 times Sydney's age and sum of their ages =75
Answers
Answer:
Devon is 50 and Sydney is 25
Step-by-step explanation:
We know that d + s = 75 and that Devon is two times Sydney's age. This can be represented by 2s + s = 75 (keep in mind that 2s = d). Simplify the equation.
3s = 75
s = 25
Now we can substitute this in the original equation.
d + 25 = 75
d = 50
Best of Luck~
Answer: Sydney=25 Devon=50
Step-by-step explanation:
Sydney's age is represented by x and since Devon is 2 times older (his/her) age would be represented as 2x. So added together would be 3x. So 3x=75. 75/3=25. So x=25 meaning that Sydney is 25 and Devons age is 50 as 25x2=50.

A. m∠C=63, b=31, c=25.1
B. m∠C=63, b=27, c=26
C. m∠C=63, b=28.1, c=22
D. m∠C=63, b=28.1, c=25.1
Answers
9514 1404 393
Answer:
D. m∠C=63, b=28.1, c=25.1
Step-by-step explanation:
The angle sum relation tells you ...
C = 180° -23° -94° = 63°
The law of sines tells you ...
b/sin(B) = a/sin(A)
b = sin(B)·a/sin(A) = sin(94°)·11/sin(23°) ≈ 28.084 ≈ 28.1
Similarly, ...
c = sin(C)·11/sin(23°) = sin(63°)·28.15235 ≈ 25.084 ≈ 25.1
__
C = 63, b = 28.1, c = 25.1

brenda bought 8 cupcakes at $1.59 each and 5 pies at $5.99 each . how much more did he spend on pie's than cupcakes
Answers
Answer:
17.23
Step-by-step explanation:
Find the cost of the cupcakes
8* 1.59= 12.72
Find the cost of the pies
5*5.99 =29.95
Subtract the cost of the cupcakes from the pies
29.95-12.72=17.23
Answer:
Money spent more on pies than cupcakes = $17.23
Step-by-step explanation:
1 cupcake = $ 1.59
8 cupcakes = 8 * $ 1.59
8 cupcakes = $12.72
1 pie = $5.99
5 pies = 5 * $5.99
5 pies = $29.95
Money spent more on pies than cupcakes = Pies - Cupcakes
Money spent more on pies than cupcakes = $29.95 - $12.72
Money spent more on pies than cupcakes = $17.23

Kim and Tom both cycle to work from their
homes, at the same speed. Kim lives 20 km
away from work, and Tom lives only 15 km
away from work. It takes Kim 1 hour more to
cycle to work than Tom. Determine how long
Tom takes to get to work.
Answers
Answer:
3 hours
Step-by-step explanation:
You find the LCM between 20 and 15, which is 5. This means that Kim and Tom are both biking at 5 miles per hour, meaning that to determine how much time Tom takes, you would do 15/5, which is 3 hours.
Time taken by Tom to get office is 3 hour
Given information:
Distance of office from Kim house = 20 km
Distance of office from Tom house = 15 km
Kim take 1 hour more
Find;
Time taken by Tom to get office
Computation:
Assume;
Time taken by Tom = a hour
So,
Time taken by Kim = (a + 1) hour
[tex]Speed = \frac{Distance}{Time}[/tex]
So,
[tex]\frac{20}{(a + 1)}=\frac{15}{a} \\\\20a = 15a + 15\\\\20a - 15a = 15\\\\5a = 15\\\\a = 3[/tex]
So,
Time taken by Tom = 3 hour

x = –2/3 or –20/9
Step-by-step explanation:
(9x+13)² = 49
Finding the square root of both sides
9x+13 = √49
9x+13 = ±7
Subtracting 13 from both sides
9x = 7 – 13 or 9x = -7 –13
9x = –6 or 9x = –20
Divide both sides by 9
x = –6/9 or x = –20/9
Simplifying
x = – 2/3 or x = –20/9
