If f(x) = 2x - 4 and g(x)= x², what is f(g(x))?
kupik [55]

Answer:

D

Step-by-step explanation:

To evaluate f(g(x)) substitute x = g(x) into f(x)

f(g(x))

= f(x²)

PLEASE HELP! I feel horrible and I'm crying so hard right now. This is due.
Lady bird [3.3K]

Answer:

62

Step-by-step explanation:

surface area of a rectangular prism = 2lw + 2lh + 2wh

Where l = length, w = width and h = height

The box has the following dimensions

length = 5 in

width = 3 in

height 2 in

Using these dimensions, we plug in the values into the formula

SA=2(5*3)+2(5*2)+2(3*2)\\5*3=15\\15*2=30\\5*2=10\\10*2=20\\3*2=6\\6*2=12\\SA=30+20+12\\30+20+12=62

Hence, the surface area = 62
