I hate my math teacher this is wat she gave me can you help mee and explained pls

( its the twelveth one plz )

Surface Area of the box is 190" or in.

Step-by-step explanation:

We start by determining the surface area formula for the box, which is a rectangular prism:

S = 2(l*w+w*h+l*h), where S = surface area of rectangular prism, l = length, w = width, and h = height.

Since length = 7", width = 2", and height = 9", we can substitute the information given into the formula above.

S = 2((7*2)+(2*9)+(7*9))

  = 2(14+18+63)

  = 2(95)

  = 190"

Surface Area of the box is 190" or in.

pls mark as brainliest

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
