If f(x) = 4x + 10, which expression represents f(x2 + 2)?

USPshnik [31]

In order to determine the answer to this item, we just have to substitute x² + 2 to all x's of the first function. That is,
f(x) = 4x + 10
will become,
f(x²+2) = 4(x²+2) + 10
Simplifying will give us an answer of,
f(x²+2) = 4x²+18

The perimeter of the rectangle shown is 36 inches. Write and solve an equation to find the value of x.

MakcuM [25]

Answer:

Step-by-step explanation:

Because we know that 1 side is 12, we can multiply it by 2 to find part of the perimeter, which is 24. Now we know that the other 2 sides add up to 12. That means that they each measure 6, so x = 3. The real question is why it shows that 6 is longer than 12!
