Find the greatest common factor for this number pair.
15, 24

3

Step-by-step explanation:

Factors of 15: 1, 3, 5, 15

Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24

Between these to factors only 1 and 3 is same factors and 3 is the greatest.

SO the GCF is 3.

b

step-by-step explanation:

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
