Question

Factor 60y-90-20x to identify the equivalent expressions. Choose two answers.

5(14-16-4x)



2(30-45-10)



5(12y-18-4x)



10(6y-9-2x)

Answer 1

C & D
Explanation:
One evident common factor between 60, 90, & 20 is 10 because all these numbers end in a 0; Therefore one way to factor the equation 60y - 90 - 20x is;
10 (6y – 9 – 2x)
5 is also a common factor between the numbers 60, 90, & 20
60/5 = 12; 90/5 = 18; 20/5 = 4
Therefore 60y - 90 - 20x is also equal to;
5 (12y – 18 – 4x)
