Answer:
C) 2(4x² + 5x - 4) is your answer
Step-by-step explanation:
Factor out common factors from all terms.
Note the factors for 8 & 10:
8: 1, 2, 4, 8
10: 1, 2, 5, 10
2 is the largest common factor, and so factor out 2
8x² + 10x - 8 = 2(4x² + 5x - 4)
C) 2(4x² + 5x - 4) is your answer
Note that you cannot factor out anymore common factor numbers or variables.

Answer:
The answer to your question is 4.5
Step-by-step explanation:
Data
hypotenuse = h = 6
angle = α = 42°
adjacent side = DE
Process
Use trigonometric functions to solve this problem
1.- The trigonometric function that relates the adjacent side and the hypotenuse is cosine
Cosα = 
Solve for adjacent side = DE
DE = hypotenuse x cos α
Substitution
DE = 6 x cos 42
Simplification
DE = 6(0.74)
Result
DE = 4.5
Answer:
The sum of the first 37 terms of the arithmetic sequence is 2997.
Step-by-step explanation:
Arithmetic sequence concepts:
The general rule of an arithmetic sequence is the following:

In which d is the common diference between each term.
We can expand the general equation to find the nth term from the first, by the following equation:

The sum of the first n terms of an arithmetic sequence is given by:

In this question:

We want the sum of the first 37 terms, so we have to find 




Then

The sum of the first 37 terms of the arithmetic sequence is 2997.
The answer is 54 feet because 15+15+12+12=54
Hope this Helps :D
