The side is (2x+3)? then the area is:
(2x+3)(2x+3) = 4 x^2 + 12 x + 9 if x = 6 then
Area = 4(36)+12(6)+9
= 144 + 72 + 9
= 225, too big :(
Answer:
answer is x=10 I hope it help
Answer:
see explanation
Step-by-step explanation:
To add/subtract the fractions we require them to have a common denominator.
The lowest common multiple of 6 and 5 is 30
Note that 1 = ![\frac{30}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B30%7D%7B30%7D)
Multiply the numerator/denominator of the first fraction by 5
Multiply the numerator/denominator of the second fraction by 6
=
-
+ ![\frac{6(4)(1-2x)}{5(6)}](https://tex.z-dn.net/?f=%5Cfrac%7B6%284%29%281-2x%29%7D%7B5%286%29%7D)
=
-
+ ![\frac{24(1-2x)}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B24%281-2x%29%7D%7B30%7D)
Distribute and simplify the numerators, leaving the denominator
= ![\frac{30-15x-30+24-48x}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B30-15x-30%2B24-48x%7D%7B30%7D)
= ![\frac{24-63x}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B24-63x%7D%7B30%7D)
