Me on this i hate math and i don't understand bc i have to do this asap

Scholar #2 is correct. You take 15=-3m-18+5m-7 and combie like terms. Which will leave you with 15=2m-25. You will simplify from there, getting 20=m.

15 = -3m - 18 +5m -7

First step is to combine like terms:

15 = 2m - 18 - 7

15 = 2m-25

Add 25 to each side:

40 = 2m

Divide both sides by 2:

m = 40/2

m = 20

Scholar 2 has the correct solution.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
