Answer:

4t+6

Step-by-step explanation:

To find the perimeter of the rectangle you add the length of the sides.

Perimeter= t+ t+ t+ 3+ t+ 3= <u>4t+6</u>

or

Perimeter=2(t)+ 2(t+3)=  2t+ 2t+ 6=  <u>4t+6</u>

Which equations are true?
Vlad [161]

Answer:

Step-by-step explanation:

1)4.5m+4.7=20m+47

4.5m-20m=47-4.7

-15.5m=42.2

m=-2.72

2)14+21w=7(2+3w)

  41+21w=14+21w

   21w-21w=14-41

3)49r+35=7(7r+35)

  49r+35=49r+245

 49r-49r=245-35

4)9(8h-3)=72h-27

  72h-27=72h-27

   72h-72h=-27+27

5)5.2+5.3t=10+15t

   5.3t-15t=10-5.2

    -9.7t=4.8

      t=4.8/-9.7

      t=0.49

6)6f+3.111=18f-33

  6f-18f=-33-3.111

  -12f=-36.111

     f=-36.111/-12

     f=3.01
