94
step-by-step explanation:
average the numbers and use a variable to figure out the minimum to get a 90.
(79+94+91+92+x)/5=90
x = 94
35/2 is it i think maybe
write out the polynomial, with leading coefficient 1:
y = 1 (x+2)^1 (x-7)^1 (x-5)^2
next time, share the answer choices. .
i think its 7.6
if so your welcome
