B. y = 2x-2
14 = 2(8) + b
14 = 16 + b
-2 = b
Y=4-7x
because it equals = -7
and
y= -5/4x + 2
because it equals = -5/4
Well if I did my math correctly I do believe the perimeter should be 392 ft.
6÷2.5= 2.4
2.4×35=84
8÷2.5= 3.2
3.2×35=112
84×2
112×2
_____
392
you mult. by 2 because it's a room which usually has four walls and I imagined it being a rectangle.
In this question, all you have to do is substitute 12 into all the places where it says x in the question.
Therefore:
g(12) = 3(12 + 8) = 3(20) = 60
So, g(12) = 60
