138 dolllars multiply 115 and .20 and add your answer with the original amount
Answer:
The value of x is -2 and 2.
Step-by-step explanation:
When solve an expression, you have to make the expression equals to 0 by moving all the terms to one side :
x² - 3x - 1 = -3x + 3
x² - 3x - 1 + 3x - 3 = 0
x² - 4 = 0
Next, you have to factorize and solve it :
x² - 4 = 0
x² + 2x - 2x - 4 = 0
x(x + 2) - 2(x + 2) = 0
(x + 2)(x - 2) = 0
x + 2 = 0
x = -2
x - 2 = 0
x = 2
The answer is b. The others don’t make sense
The equations without a solution are A, B, and D since if you were to simply multiply out the equations with FOIL, you would receive X's that cancel out on both sides. I am not sure if you are looking for one solution but here's my input
