Pretty sure this is asking for the perimeter, so just add together the length of all the sides, 30 + 30 + 18 ( 1 yard is 3 feet so just multiply that ) + 18, which equals 96 feet.

Hope this helps, if not, comment below please!!!

If f(x) = 5x + 7 and g(x) = -2x - 4 Find f(g(x)) = -10x + [?] Enter

grigory [225]

Answer:

$f(g(x)) = -10x -13$

Step-by-step explanation:

Given

$f(x) = 5x + 7$

$g(x) = -2x - 4$

Required

Find f(g(x))

This is calculated as:

$f(x) = 5x + 7$

Substitute g(x) for x

$f(g(x)) = 5(f(g(x)) + 7$

Substitute $g(x) = -2x - 4$

$f(g(x)) = 5(-2x - 4) + 7$

Open bracket

$f(g(x)) = -10x - 20 + 7$

$f(g(x)) = -10x -13$

If a high school with 330 students wanted a ratio of 15 students per teacher, how many teachers would they need?

KengaRu [80]

They would need 22 teachers to have 15 students per teacher because 22*15=330
