Step-by-step explanation:
<u>Right Triangles</u>
The ratios of the sides of a right triangle are called trigonometric ratios. Each acute angle has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.
The tangent ratio is defined as:
The opposite side is 25 and the adjacent side is 18, thus:
The angle is calculated by using the inverse tangent function:
The y is the same for both equations. Equate them
-x - 5 = 2x + 4 Add x to both sides
- 5 = 3x + 4 Subtract 4 from both sides.
- 9 = 3x Divide by 3
x = -9 / 3
x = - 3
y = - x - 5
y = -(-3) - 5
y = - 2
So that point is where the two equations meet.

Answer:
3n^2(n^2+7n+9)
Step-by-step explanation:
Find the common factor. In this case, it is 3n^2. Take out the common factor of the integers.
So, therefore it is
3n^2(n^2+7n+9)
