2x-10=44+8x
subtract 2x from each side
8x-2x=6x
now we have -10=44+6x
subtract 44 from both sides
-10-44=-54
now we have -54=6x
divide both sides by 6
-54/6=-9
so x=-9
The new perimeter will be 3 times the old perimeter.
Original perimeter:
2(8+7) = 2(15) = 30 yds
New perimeter once they are tripled:
3 x 8 = 24
3 x 7 = 21
2(24+21) = 2(45) = 90 yds
30 x 3 = 90
Hii the answer is 29 i’m pretty sure
Answer:
Given the expression: ![3y^3-2y[4y-y(y-3)]-[2y(y+1)-3y(y^2-1)]](https://tex.z-dn.net/?f=3y%5E3-2y%5B4y-y%28y-3%29%5D-%5B2y%28y%2B1%29-3y%28y%5E2-1%29%5D)
The distributive property says that:

Applying distributive property on the given expression, we have;
![3y^3-2y[4y-y^2+3y]-[2y^2+2y-3y^3+3y]](https://tex.z-dn.net/?f=3y%5E3-2y%5B4y-y%5E2%2B3y%5D-%5B2y%5E2%2B2y-3y%5E3%2B3y%5D)
again apply the same property we have
![3y^3-8y^2+2y^3-6y^2-[2y^2+2y-3y^3+3y]](https://tex.z-dn.net/?f=3y%5E3-8y%5E2%2B2y%5E3-6y%5E2-%5B2y%5E2%2B2y-3y%5E3%2B3y%5D)
or

Like terms are those terms which have same variables to the same power.
