$\bf 4(x+1)^{\frac{2}{3}}+\cfrac{12}{(x+1)^{\frac{1}{3}}}\impliedby \textit{so, our LCD is }(x+1)^{\frac{1}{3}}
\\\\\\
\cfrac{4(x+1)^{\frac{2}{3}}\cdot (x+1)^{\frac{1}{3}}+12}{(x+1)^{\frac{1}{3}}}\implies \cfrac{4(x+1)^{\frac{2}{3}+\frac{1}{3}}+12}{(x+1)^{\frac{1}{3}}}
\\\\\\
\cfrac{4(x+1)^{\frac{3}{3}}+12}{(x+1)^{\frac{1}{3}}}\implies \cfrac{4(x+1)+12}{(x+1)^{\frac{1}{3}}}\implies \cfrac{4x+4+12}{(x+1)^{\frac{1}{3}}}
\\\\\\
\cfrac{4x+16}{(x+1)^{\frac{1}{3}}}\implies \cfrac{4(x+4)}{\sqrt[3]{x+1}}$

Can someone help me on this

Sidana [21]

Answer:

Area = 702.9 or 703

Step-by-step explanation:

By Pythagoras the. first, we need to find the base!

(H)2 = (P)2 + (B)2

(82)2 = (18)2 + b2

6724 = 324 + b2

b2 = 6724-324

b2 = 6100

b = √6100

b = 78.1

note - they all are in square

Now, area of the triangle:-

1/2 * b * h

1/2 * 78.1 * 18

= 702.9

Hope it helps!
