Break into 2 equatins to get x's:
2x-6<4 and 2x-6>-4
Solve for x in both:
2x-6<4
2x<10
x<5
2x-6>-4
2x>2
x>1
Graph both inequalities on the same number line:
<---0-----1-----2-----3-----4-----5-----6--->
(a)

= 400
(b)


(c) Only the positive solution makes sense because you cannot have a negative side length.
(d) Since one side of the painting is 20 inches, all four sides together will be 20*4 = 80 inches

Answer:
Step-by-step explanation:
x²-x-30=0
x² - 6x + 5x - 30 = 0
(x² - 6x) + (5x - 30) = 0
x(x - 6) + 5(x - 6) = 0
(x + 5)(x - 6) = 0
x + 5 = 0 or x - 6 = 0
x = -5 or x = 6
