Answer:
615
Step-by-step explanation:
The ratio of the given terms can be used to find the common ratio between terms:
a5/a2 = (a1·r^(5-1))/(a1·r^(2-1)) = r^3 = 768/-12 = -64
r = ∛-64 = -4
So the first term is ...
a1 = a2/r = -12/-4 = 3
And the first 5 terms of the series are ...
3 + (-12) + (48) + (-192) + 768 + ...
The sum of the first 5 terms is 615.
Pretty much trade. You give vendor money or currency in return they give you the thing you paid for.

Answer:
26
Step-by-step explanation:
Let x represent the missing number
Convert both fractions to improper fractions
Cross multiply
Subtract both sides by 1,575
Divide both sides by 15
x = 26
Answer:
= 30mn^4
Step-by-step explanation:
The area of a trapezoid
A = 1/2 (a+b) *h
where a and b are the top and bottom
A = 1/2( 3mn^2+ 9mn^2) * 5n^2
Combine like terms
A = 1/2(12mn^2) * 5n^2
=6mn^2 * 5n^2
= 30mn^4
