Solution
The sequence is an Arithmetic sequence.
Here the 1st term = -13
An = A(n-1) + 4
Therefore, the common difference (d) = 4
2nd term = first term + common difference
2nd term = -13 + 4 = -9
The answer is -9.
Using complementary angles, it is found that F = 47º.
<h3>What are complementary angles?</h3>
Two angles are complementary if the sum of their measures is of 90º.
If two angles A and B are complementary, the sine of one angle is the cosine of the other.
In this problem, 43º and 47º are complementary, hence:
sin 43º = cos 47º, which means that F = 47º.

First you need to distribute the 9.
So 9 times 3 and 9 times 2
The Algebraic should look like now: (27^3x-18)
So the final answer is: 
You cannot simplify it anymore because there are <u>no like terms left.</u>
Answer:
<u>164</u>
Step-by-step explanation:
Finding the Surface Area :
- Area (2 triangles) + Base rectangle + Left rectangle + Right rectangle
- 2 x 1/2 x 4 x 5 + 9 x 5 + 6 x 9 + 5 x 9
- 20 + 45 + 54 + 45
- 65 + 99
- <u>164</u> cm²
