Answer:

Step-by-step explanation:

By the Pythagorean Theorem we know

h^2=x^2+y^2 (where h is the hypotenuse and x and y are sides of a right triangle)

w^2+18^2=30^2

w^2=30^2-18^2

w^2=900-324

w^2=576

w=24 in

ValentinkaMS [17]

Answer:

a. 40

Step-by-step explanation:

Given

$g(x)=2x$ and $h(x)=x^2+4$

$(h\circ g)(x)=h(g(x))$

$(h\circ g)(x)=h(2x)$

We plug in 2x into $h(x)=x^2+4$ .

$(h\circ g)(x)=(2x)^2+4$

$(h\circ g)(x)=4x^2+4$

We now substitute x=-3.

$(h\circ g)(-3)=4(-3)^2+4$

$(h\circ g)(-3)=36+4=40$

The correct choice is A.
