Answer:
-10y + 18 = -3 (5y - 7) + 5y
-10y + 18 = -18y + 21 + 5y
-10y + 18 = -13y + 21
Step-by-step explanation:
-10y + 18 = -3 (5y - 7) + 5y
-10y + 18 = -18y + 21 + 5y
-10y + 18 = -13y + 21

![2\sqrt[3]{3}](https://tex.z-dn.net/?f=2%5Csqrt%5B3%5D%7B3%7D)
Step-by-step explanation:
Hi
As we have 24 Superscript one-third, this is ![(24)^{\frac{1}{3}} =\sqrt[3]{24}](https://tex.z-dn.net/?f=%2824%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%20%3D%5Csqrt%5B3%5D%7B24%7D)
.
![\sqrt[3]{24}=\sqrt[3]{8*3}=\sqrt[3]{8} \sqrt[3]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B24%7D%3D%5Csqrt%5B3%5D%7B8%2A3%7D%3D%5Csqrt%5B3%5D%7B8%7D%20%5Csqrt%5B3%5D%7B3%7D)
, therefore
![\sqrt[3]{8} =2](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8%7D%20%3D2)
, so ![\sqrt[3]{8} \sqrt[3]{3}=2\sqrt[3]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8%7D%20%5Csqrt%5B3%5D%7B3%7D%3D2%5Csqrt%5B3%5D%7B3%7D)

Answer:
x^2y^2 +9xy^2-xy-27y-6
Step-by-step explanation:
(xy+9y+2) (xy-3)
Each term of second bracket will be multiplied with the terms of first bracket
= xy(xy+9y+2) -3(xy+9y+2)
= x^2y^2+9xy^2+2xy-3xy-27y-6
=x^2y^2+9xy^2-xy-27y-6
