Answer: X=1.5

Step-by-step explanation:

Solution

Perimeter= 2(l+w)

25= 2( 3x+4 +2x+1)

25= 2(3x+2x+4+1)

25= 2(5x+5)

25= 10x+10

Now subtract 10 on both sides..

25-10= 10x+10-10

15=10x

Now divide 10 on both sides to get x

15/10= 10x/10

1.5=X

Add 3/7 + 8/9 . Simplify the answer and write as a mixed number

Fudgin [204]

You will get both of the fractions over the same denominator, so it will be 27/63 and 56/63, then you will add the two numerators, so it will then come out to 83/63, and you will then simplify that by subtracting 63 from 83, and will get 1 20/63
