Answer:
Its below!
Step-by-step explanation:
a=l*w
9=(3+x) (2+x)
9=6+3x+2x+x^2
9=6+5x+x^2
3=5x+x^2
Hope this helps!! :)
We write this like this:
49=35%x
and we want to find the x.
let's invert the sides:
35%x=49.
35 is equal to 0.35
0.35*x=49
and now we only divide both sides by 0.35:
x=140
so the answer is 140.
(aternatively we can do it through fractions:
35/100*x=49
divide both sides by 7:
5/100*x=7
simplify the first fraction
1/20*x=7
and multiply by 20:
x=140
