ANSWER: $84
EXPLANATION:
We need to know the surface area of the room with the specified dimensions.
A = 2(wl + hl + hw)
w = 12
h = 8
l = 16
A = 2( (12 * 16) + (8 * 16) + (12 * 8) )
A = 2(192 + 128 + 96)
A = 2(416)
A = 832 square feet
832 / 150 = 5.546666666666667
(Round that up to the next whole number)

Answer:
-26
Step-by-step explanation:
- Insert the f(-1) into the equation.
- It'll be f(-1) = 6(-1) + 13(-1) + 2(-1) - 5
- After you times all of it. You'll get 7-13-2-5
- Solve it and you'll get -26

Step-by-step explanation:
Formula for finding the axis of symmetry: x = -b/2a
x^2 - 2x - 15
a = 1; b = -2 (plug these into the formula above)
-(-2)/2(1) = 2/2 = 1
