Answer:
94 or 95
Step-by-step explanation:
91 + 95 + 87 + 83 = 356
356/4 =89
average so far is 89
356 + 94 = 450
450/5 = 90
356 + 95 = 451
451/5= 90.2
Answer:
ab(ab + 20)
Step-by-step explanation:
Because we see both terms have at least one ab in it, we can factor out ab and get ab(ab + 20). However, because ab^2 does not have any coefficient, there is nothing more to factor out. Thus, ab is your greatest common factor, or GCF.
R = d/2 = 10
common area = (2/3)πr^2 - (rt(3)/2)r^2
