Factor Completely:

5x2 + 10x - 40

5(x+4) (x-2)

Step-by-step explanation:

5x^2 + 10x - 40

Factor out a 5

5(x^2 +2x - 8)

Looking at the inside of the parentheses

What 2 numbers multiply to -8 and add to 2

4 *-2 = -8

4+-2 = 2

5(x+4) (x-2)

Given.

Factor out the GCF.

Use AC method.

Find product of b (-8) and sum of c (2x).

(-2,4)

When you solve.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

the number of the people going.

step-by-step explanation:
