2m - m - 7m simplified is

-6m

Step-by-step explanation:

You can change the "m" in the equation to 1m so if I re-write the problem with this new information it is as follows, 2m-1m-7m So first we take a look at the first portion of the equation and that is, 2m-1m. Which is pretty much a no-brainer, we get 1m or just m. Then we take a look at the second portion of the equation which again, is as follows, 1m(or m)-7m. 1-7=-6 so if the answer with no variable is -6 then just add your variable on the end and get a final answer of...-6M

I hope this answer was not confusing and could help you out a bit. If you would be so kind, please mark this answer brainliest.  

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

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
