Question

(1/2r+3/4r) (1/2r+3/4y)​

Answer 1

QUESTION:

$( \frac{1}{2} r + \frac{3}{4}r )( \frac{1}{2} r + \frac{3}{4} y)$

Step-by-step explanation:

$\frac{1}{2}r ( \frac{1}{2}r + \frac{3}{4} y) + \frac{3}{4} r( \frac{1}{2} r + \frac{3}{4} y)$

$= \frac{1}{4} {r}^{2} + \frac{3}{8} ry + \frac{3}{8} {r}^{2} + \frac{9}{16} ry$

$= \frac{1}{4} {r}^{2} + \frac{3}{8} {r}^{2} + \frac{3}{8} ry + \frac{9}{16} ry$

$= \frac{2 + 3}{8} {r}^{2} + \frac{6 + 9}{16} ry$

$= \frac{5}{8} {r}^{2} + \frac{15}{16} ry \: ( answer)$
