Please help i dont know what to do for #1 we never went over it. Help asap Please. You migjt have to flip devoce upside down to see

. GCF of first two terms is 7r^2.

GCF for last two terms is 2

Step-by-step explanation: GCF means the largest number that the terms can be divided by evenly.

7 and 14 are both divisible by 7. The factors of those terms are (7r^2)(r +2).

r^3 means r × r × r. r^2 means r × r so r^2 is a factor of r^3

2r and 4 are both divisible by 2. The factors of those terms are (2)(r +2)

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
