Answer:

the other sides are 9 and 12

Step-by-step explanation:

use the Pythagorean theorem.

a^{2} +b^{2} =c^{2}

you know that c^2 is 225 because 15*15=225

a^{2} +b^{2} =225

(from here on I just plugged numbers in)

3:4=9:12

9^{2} +12^{2} =225

81+144=225

225=225

Yaaaaay!

그는 [d (7x2 + 37 0) 를 0 (24 3) 4 10 ○ (7x2+3) 4+c ○ (x3)6+c 급 (7x + 3) 6 5
IRINA_888 [86]

the given expression is,

\int \frac{x}{(7x^2+3)^5}dx

take P = 7x^2 + 3

differentiate the function,

\begin{gathered} dp=14x\times dx \\ xdx=\frac{dp}{14} \end{gathered}

put the values.,

\int \frac{1}{14}\frac{dp}{p^5}\begin{gathered} =\frac{1}{14}\int \frac{dp}{p^5} \\ =\frac{1}{14}\times\frac{P^{-5+1}}{-5+1}+C \end{gathered}\begin{gathered} =\frac{1}{14}\times\frac{1}{-4}P^{-4}+C \\ =-\frac{1}{56}P^{-4}+C \end{gathered}

now put the value of P = 7x^2 + 3

=-\frac{1}{56}(7x^2+3)^{-4}+C

thus, the correct answer is option A
