Y= -3 . Plug the -2 into x. 8x-3y=-7
8(-2) -3y= -7
To find the surface area of the rectangular prism, use the formula:
A=2(wl+hl+hw)
Note that: w = 4, l = 12, h = 3
plug into the equation
A = 2((4)(12) + (3)(12) + (3)(4))
Simplify
A = 2(48 + 36 + 12)
A = 2(96)
Multiply
A = 96 x 2
A = 192
192 m³ is the surface area of the rectangular prism.

Answer:
-50k+27
Step-by-step explanation:
=(−5)(1)+(−5)(2k)+(−8)(−4)+(−8)(5k)
=−5+−10k+32+−40k
Combine Like Terms:
=−5+−10k+32+−40k
=(−10k+−40k)+(−5+32)
=−50k+27
