HELP ME PLS I NEED THIS TODAY Explain how you would simplify the expression 3x + 7y - 2x + 3y + 7? What are the "like terms"? What is your answer?

3x-2 equals 1x

7y+3y= 10y

1x+10y+7

Step-by-step explanation:

to simplify the expression you combine like terms. The like terms are ay 2 terms with the same letter so the x's together and y's together.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
