1. factor the following using the gcf: 10xy3 - 25x2y2 + 15xy
a. 5x(2y2 - 5xy2 + 3y)
b. 2x(5y3 - 12xy2 + 7y)
c. 5xy(2y2 - 5xy + 3)
2. solve by factoring the gcf: 16x2 - 4x = 0
a. {0, 4}
b. {0, 1/4}
c. {-1, 4}
d. {4, -4}

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)

yes
