A = b+5
ab = 3300
(b+5)b = 3300
b² +5b -3300 = 0 (quadratic formula)
b=55
a=60 (by first relation)

hope this answers ur question!!
Answer:
Definitely 3/4!
Step-by-step explanation:
Option A = 7.5
Option B = 66.6%
Option C = 75% (because 25 times 4 is equal to 100%, so 25 times 3 would be 75)
Option D = 6/10 or 60%
Answer:
A
Step-by-step explanation:
f(x)+g(x)=-3x^2+4x+4+x(-7x-7)= -3x^2+4x+4 -7^2-7x
= -10x^2-3x+4
