2
−4x−5.
(x-5)(x+1)=0(x−5)(x+1)=0
2 Solve for x.
x=5,-1x=5,−1
Step-by-step explanation:
A ratio is is statement of how two nummber's compare
Evaluate the expression using x = –1 and y=3.

1. Substitute the values for the variables.
we plug in -1 for x and 3 for y


2. Identify grouping symbols, beginning with the innermost symbols.

We take exponent and then we multiply
3. Determine and apply the rules of exponents to simplify

(-1)^4 = -1 * -1 * -1 * -1 = 1
(3)^3 = 3*3*3= 27

4. Evaluate.

162
The value of the expression is 162
