Answer:
Step-by-step explanation:
I = -425x^2 + 45,500(x) - 650,000
x = 40
I = -425(40^2) + 45,500(40) - 650,000
I = -425(1600) + 1,820,000 - 650,000
I = -680,000 + 1,820,000 - 650,000
I = 1,820,000 - 1,330,000
I = 490,000 <===
3x + 21
(3)(x+7)
Now, we distribute the 3 in each term of (x+7)
So, 3*x = 3x and 3*7 = 21.
So our resulting term would be 3x+21.
54.9 because it is the answer

I dont know how far you wanted me to round so you will have to do that part
