You first would have t multiply 5x and x and then 5x and -2y.
5x^2-10xy is your answer.
Four times a number plus twenty one

no equation given ,pls mention it in the comments
Answer:
12920
Step-by-step explanation :
distance covered = d = ∫
a = t = 20
b = t = 0
f'(t) = 646 : f'(t)² = 417316
g'(t) = 5 : g'(t)² = 25
d =
t = 20 & t = 0
d = 646t
d = 646*20 = 12920
