Answer:
The second base of the trapezoid b2 is 2.5 inches
Step-by-step explanation:
Here, we want to calculate the second base of the trapezoid.
Mathematically, the area of a trapezoid can be given as;
A = 1/2(a + b) h
where a and b represents the parallel bases and h is the height of the trapezoid
so this, we have from the question
1/2(4.5 + b2) * 6 = 21
3(4.5 + b2) = 21
divide both sides by 3
4.5 + b2 = 7
b2 = 7-4.5
b2 = 2.5 inches

A is the answer I'm sure of it
Whole numbers cannot have fractional components and 2/15 is a proper fraction; therefore, it cannot be made into a mixed number either

Answer:
2 a^3 b ^3/4 * 3^1/2
2 a^3 b ^3/4 9^ 1/4
Step-by-step explanation:
(144 a^12 b^3) ^ (1/4)
Rewriting
12 ^2 ^1/4 a^12^1/4 b^3^1/4
We know a^b^c = a^ (b*c)
12 ^ 1/2 a^3 b^3/4
(4*3) ^ 1/2 a^3 b^3/4
We know (ab)^c = a^c * b^c
4^1/2 * 3^1/2
2 a^3 b ^3/4 * 3^1/2
Rewriting 3 as 9 ^ 1/4
2 a^3 b ^3/4 9^ 1/4
