The last step of an equation whose solutions are x=-10 and x=-5 is:
(x+10)(x+5)=0
We need to add some previous steps, which make the equation an absolute value equation.
A way to do this, is writing |(x+10)(x+5)|=0,
the only solutions are still x=-10 and x=-5
Answer: |(x+10)(x+5)|=0
Answer: 1
Step-by-step explanation:
Plug in 4 for x and 3 for y to get:
(4 + 3)^0
Trick: Anything raised to the 0th power is 1
(For example, 500 to the 0th power is equal to 1)
so... (7)^0 = 1

Answer:
Width = 7 units
Step-by-step explanation:
Length = x units
Width = (x -1) units
Area = 56 square units
length * width = 56
x * (x - 1) = 56
x*x - x*1 = 56
x² - x - 56 = 0
x² -8x + 7x - 7*8 = 0
x(x - 8) + 7(x - 8) = 0
(x - 8)(x + 7) = 0
Here, (x +7) is ignored because measurement will not in negative.
x - 8 = 0
x = 8
Length = 8 units
Width = 8-1 = 7 units
