Answer:

p(20) = 4460

Step-by-step explanation:

Given

p(x) = -10x^2 + 498x - 1500

Required

Evaluate p(x) when x = 20

To do this, we simply substitute 20 for x

p(x) = -10x^2 + 498x - 1500

p(20) = -10 * 20^2 + 498 * 20 - 1500

p(20) = -10 * 400 + 9960 - 1500

p(20) = -4000 + 9960 - 1500

p(20) = 4460
