Question

please answer the Q.no =13,please its urgent , question is given in the above picture​

Answer 1

16

Step-by-step explanation:

$f(x) = 2 {x}^{2} + 16x + 5p$

Given,

$f( - 3) = 2 { ( - 3)}^{2} + 16( - 3) + 5p = 50$

Or,

$18 +( - 48) + 5p = 50$

$-30 + 5p = 50$

$5p = 50 + 30 = 80$

$p = \frac{80}{5} = 16$

PLEASE MARK BRAINLIEST...

Answer 2

$\tt16x + 2 {x}^{2} + 5p = 50$

$\tt{Putting~x~=~-3}$

$\tt16 \times - 3 + 2 \times { - 3}^{2} + 5p = 50$

$\tt - 48 + 2 \times 9 + 5p = 50$

$\tt - 48 + 18 + 5p = 50$

$\tt - 30 + 5p = 50$

$\tt5p = 50 + 30$

$\tt5p = 80$

$\tt \: p = \frac{80}{5}$

$\rm \: p = 16$

Hope it helps :)
