A square patio has a perimeter of (32x+8) feet. What is the length of the patio? Thanks!
Flauer [41]

Answer:

The side length is 8x+2 ft

Step-by-step explanation:

The perimeter of a square is found by

P =4s  where s is the side length

32x +8 = 4s

Divide each side by 4

32x/4 +8/4 = 4s/4

8x+2 = s

The side length is 8x+2 ft

Steve is 5 times as old as Janis. In 12 years, he will be twice as old as she will be then. How old are they now?
Alex17521 [72]
Write this story as equations:

s = 5j
(s+12) = 2*(j+12)

Then solve:

5j+12 = 2j + 24 => 3j = 12 => j=4, s=5*4=20

Steve is 20, Janis is 4
In 12 years they will be 32 and 16

Let f = {(–2, 4), (–1, 2), (0, 0), (1, –2), (2, –5)}. Let g = {(–3, 3), (–1, 1), (0, –3), (1, –4), (3, –6)}. What is g(f(2))? -5
Andreyy89
First find the value of f(2). This is the y coordinate of the point with x = 2 as the x coordinate. Look through the set f and see that (2,-5) is one of the points. This point says x = 2 and y = -5. So f(2) = -5

We will replace the f(2) with -5 to go from this
g(f(2))
to this
g(-5)

Now repeat the same steps but for g this time
Look through the set g for a point with x coordinate of -5. That point is NOT listed. Why not? Because the x values are -3, -1, 0, 1 and 3. None of which are -5.
No such point exists.

Final Answer: The composition is undefined

Solve for b.
Over [174]

Answer: A.) b= 2a/h-c

1/2h(b+c)= A

2×1/2h(b+c)=A×2

h(b+c)=2A

h÷h(b+c)=2A÷h

b+c=2A/h

b+c-c=2A/h-c

b=2A/h-c

I hope this is good enough:
