they increased by 70 percent. divide 667 by 912 and you get 0.67237903 but you round to the tenths and get 70% because you move the decimal to the right twice
By the binomial theorem,
For i = 1, the corresponding term in the expansion is
so that ap = 20, while for i = 2 we get
so that a²p(p - 1)/2 = 160.
Solve for a and p. Observe that
(a²p(p - 1)/2) / (ap) = 160/20
a(p - 1)/2 = 8
ap/2 - a/2 = 8
10 - a/2 = 8
a/2 = 2
a = 4
and it follows that
ap = 20
4p = 20
p = 5
Answer:-6/2
Step-by-step explanation:I think this is the answer because you have to cross muitply.
