x = -33
Step-by-step explanation:
2/3(x+6)=-18
Multiply each side by 3/2
3/2*2/3(x+6)=-18*3/2
x+6 = -27
Subtract 6 from each side
x+6-6 = -27-6
x = -33
Answer:
Width = (x + 8) inches.
Step-by-step explanation:
The area of the quilt is the length times the width and if we know the area and the length we can find the width by area / length.
Area = x^2 + 18x + 80 = (x + 10)(x + 8) - now we know that the length is (x + 10) so the width must be (x + 8) inches.

Answer:
3x=42
Divide 3x to both sides
14=x
56=8x
Divide 8 to both sides
7=6
6x+4=40
subtract 4 to both sides
6x=36
divide 6 to both sides
x=6
58=4x-6
add 6 to both sides
64=4x
divide 4 to both sides
16=x
