Factor out the greatest common factor from this expression using the distributive property. 90 + 60 a) 30(3+2) b) 10(9+6) c) 15(6+4) d) 6(15+10)

30(3+2)

Step-by-step explanation:

90=3(30)=3(3)(10)=3(3)(2)(5)

60=3(20)=3(5)(4)=3(2)(2)(5)

The factors that 90 and 60 have in common are a pair of 3,2, and 5's.

So the biggest factor we can factor out is 3*2*5 which is 30

So 30(3+2)

Leftovers from the prime factorizations above stayed in the ( )

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
