Hope it helps ^_^
Answer:
x = 6, -8
Step-by-step explanation:
If (x - 6)(x + 8) = 0, that would imply that either (x - 6) or (x + 8) would equal zero. Using this, we can find that solving the two equations:
x - 6 = 0
and
x + 8 = 0
would yield the two solutions to the equation.
x - 6 = 0
Add 6 to both sides of the equation.
x = 6
So one of the solutions would be x = 6.
x + 8 = 0
Subtract 8 from both sides of the equation.
x = -8
So the other solution would be x = -8.
The two solutions are x = 6 and x = -8.
I hope you find my answer and explanation to be helpful. Happy studying.
Answer:
x = 17
Step-by-step explanation:

Answer:
x = 3
width = 15
Step-by-step explanation:
perimeter of a rectangle = 2 * width + 2 * length
54 = 2 * width + 2 * length = 2 * (4x) + 2*(5x) = 8x + 10x + 18x
54 = 18x
divide both sides by 18 to isolate x
x = 3
width = 5x = 5 * 3 = 15
