<span>x(x+2)+x(x-3)
=x^2 + 2x + x^2 - 3x
= 3x^2 - x</span>
6x-2(3x+2)=-4.
that would reduce after distributing the negative two to the parentheses as:
6x-6x-4=-4.
that can be reduced because the x’s cancel out. when you move the -4 over by adding 4, those cancel out too. therefore, the answer is infinite. hope this helps!!
7(z +2) - 3z =44
Distribute the 7. Distributive property: a(b+c) = ab + ac
7z + 14 - 3z = 44
Simplify like terms.
4z + 14 = 44
Subtract 14 to both sides
4z = 30
Divide by 4 on both sides.
z = 7.5
The volume is 240ft^3. v=Ah/3. v=(72)(10)/3. v=720/3. v=240.
