Answer 1

19. what is the simplified form of 4z^2+16z+15/2z^2-z-15
20. what is the siplifed form of y^3+2y-8/y^2+7y+12

Answer 2

10.
\[\frac{\frac{4x}{3}}{\frac{1}{3}}=5\]\[\frac{4x}{3}={\frac{5}{3}}\]\[4x=5\]\[x=?\]

Answer 3

11.
\[\frac{x+2}{3}-\frac{x+1}{2x}\] \[=\frac{(x+2)(2x)}{3(2x)}-\frac{3(x+1)}{3(2x)}\] \[=\frac{(x+2)(2x)-3x-3}{3(2x)}\] \[=\frac{2x^2+4x-3x-3}{3(2x)}\] \[=\frac{2x^2+x-3}{6x}\] So, what's the answer?

Answer 4

\[\frac{5}{y^2}-\frac{4}{3y}\]\[=\frac{15}{3y^2}-\frac{4y}{3y^2}\]\[=\frac{15-4y}{3y^2}\]

Answer 5

The above one is 12

Answer 6

13
\[\frac{8x^4}{12y^3} •\frac{ 20y^8}{6x^6}\]\[=\frac{2x^4}{3y^3} •\frac{ 10y^8}{3x^6}\]\[=\frac{2(10)y^5}{3(3)x^2} \]\[=\frac{20y^5}{9x^2}\]
