Answer 2

Answer:

The value is 225

Step-by-step explanation:

We have been mentioned here that we have to calculate the value of the given polynomial at x = 5. For this we will put the given value of x in the polynomial and find the value as below:

Putting x = 5 in p(x) =  $4x^{2} + 20x + 25$

p (x) = $4x^{2} + 20x + 25$

∴ p(5) = $4 (5)^{2} + 20 (5) + 25$

= 4 × 25 + 100 + 25

= 100 + 125

= 225

Therefore the answer is 225
