x+4+3x=72
4x+4=72
4x=72-4
4x=68
4x/4=68/4
x=17
Answer:
56x
Step-by-step explanation:
Think of it an a triangle and a rectangle. The area of the rectangle is obviously 13 x 4x, which is 52x
for triangle, the hypotenuse is C, Right hand side is B and the side that is in the shape is B.
Area of triangle = (bh) / 2
B = 13 - 9, so B = 4
A = 6x - 4x, so A = 2x
the area is 2x x 4, which is 8x.
8x / 2 = 4x
The area is 4x + 52x, so the final answer is 56x
(3+5)/(2+2) = 8/4 = 2
Y = 2x + b
3 = 2(2) + b, b = -1
Equation: y = 2x - 1
