Answer:
127
Step-by-step explanation:
so h(g(-5)) means that solve the function in a specific way. This means that solve for function h but the x is the answer to function g when x is -5. So first what u do is solve for g. Plug -5 in so u get -5-3 which is -8. Then u plug in -8 to function h. U have 2(-8)^2-1. Then u solve the square which is 64. Then u multiply that by 2 to get 128. Then u minus one to get ure final answer of 127. Hope this helps :D
3/4 = 0.75
each friend gets 0.75 of a bar
We could solve for x, but notice that the same expression is being squared in both (x+1)
if (x+1)^2 - 3 = 22 then
(x+1)^2 = 25
that would mean that (x+1)^2 - 5 = 25 - 5 = 20

Answer: B, 70 inches.
Step-by-step explanation:
Let's start slow and go shape by shape.
Based on the information we have, we know that the length for the rectangle is 8 inches by 7 inches. 8*7 = 56, so we have one of the answers.
Next, we do the triangle. Based on the information we have, we know that the triangle is 4 inches by 7 inches divided by 2. 4*7 = 28 
Adding 14 and 56, we got the answer to be B, 70 inches.
