Answer:
88 inches
Step-by-step explanation:
Divide the shape into 2 shapes and add all side lengths.
20+8+8+16+12+24=88
This is always true: To shift a function left,add inside the function's argument: f (x + b) gives f (x) shifted b units to the left. Shifting to the right works the same way; f (x – b) is f (x) shifted b units to the right.
So choice A is the right choice.

Answer: 155
Step-by-step explanation:
180 - 25 = 155
f(x) = 2(x^2 + 14x + ) - 5 2 is taken out of first 2 terms.
f(x) = 2(x^2 + 14x + (14/2)^2 ) - 5 - 2(14/2)^2
<em><u>2 steps </u></em>
- Inside the brackets: Linear term's coefficient (14) divided by 2 and squared
- Outside the brackets: (14/2)^2 multiplied by 2 and subtract so that there is no change in the value of the quadratic.
f(x) = 2*(x + 7)^2 - 103
The graph is of the original quadratic.
