Answer:
x + 8
Step-by-step explanation:
1. To simplify this expression, we have to combine like terms.
- (-4x + 2x + 3x) + (8)
- (-2x + 3x) + (8)
- x + 8
Therefore, the answer is x + 8.
Answer:
Your graph would start at the point 0,2 (over 0 up 2). Other points would be (2,8), (4,14), (-2,-4), and so on. A good website for graphing is Desmos.com .you can plug an equation in and it will graph it for you!

Step-by-step explanation:
Using the sum/ difference → product formula
cos x - cos y = - 2sin(
)sin (
)
sin x - sin y = 2cos (
)sin (
)
Given
(cosA - cosB)² + (sinA - sinB )²
= [ - 2sin(
)sin(
) ]² + [ 2cos(
)sin(
) ]²
= 4sin² (
)sin² (
) + 4cos² (
)sin² (
)
= 4sin² (
)[ sin² (
) + cos² (
) ← sin²x + cos²x = 1
= 4sin² (
) × 1
= 4sin² (
) = right side ⇒ proven
Y = 9/2x is in slope intercept form (y = mx+b) where m represents the slope and b represents the y-intercept.
In this case, 9/2 is the slope.
The surface area of this is letter B.
