Sorry I just need a little more info.
Answer:
The answer of the given expression is 
.
Step-by-step explanation:
Given 
.
Step 1 : Firstly we have to solve for brackets, adding the fraction with digits. For this we have to multiply 3 and 2 by 2 by 2 which gives the same denominator.
Step 2 : Fraction under the brackets is solved now we have to multiply the result with 3 to remove the brackets.
Step 3 : Now we have an expression with same denominator, here simply add and we get the result.
Hence the solution for given expression is .
There exists a similar question where m angle 2 is 9y + 4. If the angles are supplementary, the sum of their measures is 180 degrees. The equation that represents this situation is,
4y + 7 + 9y + 4 = 180
The value of y is equal to 13. The value of the measure of angle 2 is equal to 121 degrees.

Answer:
Option A = 113.04in^2
Step-by-step explanation:
Question: What is the total surface area of the cylinder? If the radius is 2in and height is 7in.
A) 113.04 in.2
B) 100.48 in.2
C) 131.88 in.2
D) 69.08 in.2
Solution:
Total surface area of a cylinder = 2πr^2 + 2πrh
r = radius = 2in
h = height = 7in
Let π = 3.14
Total surface area of the cylinder =
2×π×2^2 + 2×π×2×7
= 8π + π×28
= 8×3.14 + 3.14×28
Total surface area of the cylinder = 113.04in^2
=113.04in^2 (option A)
