3w + 6 - 4w + 3b + 2 +2b=

The answer is 5b - w + 8

Step-by-step explanation:

-w + 5b + 8

Step-by-step explanation:

Step 1: Since you're only dealing with addition and subtraction, the easiest method is to convert all subtraction to addition by adding the opposite. There is only one case of subtraction (-4w) which can be changed to adding negative 4w:

3w + 6 + (-4w) + 3b + 2 + 2b

Step 2: Combine like terms to simplify:

3w + (-4w) = -w

3b + 2b = 5b

6 + 2 = 8

-w + 5b + 8

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
