Length times width equals area of a rectangle

Length=3x

Width=x

(3x)(x)=75

3x squared=75

x=5

Length=3(5)

Length=15

Width=5

Perimeter=2(length plus width)

Perimeter=2(15+5)

=2(20)

=40

Can you show your work for this 4m-5(3m+10)=126

earnstyle [38]

Answer:

m=−16

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4m−5(3m+10)=126

4m+(−5)(3m)+(−5)(10)=126(Distribute)

4m+−15m+−50=126

(4m+−15m)+(−50)=126(Combine Like Terms)

−11m+−50=126

−11m−50=126

Step 2: Add 50 to both sides.

−11m−50+50=126+50

−11m=176

Step 3: Divide both sides by -11.

−11m /−11 = 176 /−11

m=−16
