10x-20=10x-20, make your decision on the answer from this which they are all real numbers. Hope this will help you!
The answer is 42.
The question is asking for angle N. We know from the question that angle N is equal to angle E (Don't think about the scale factor because it only applies to the sides. They're just trying to trick you).
To find angle E:

Move numbers to the right side:

Combine like terms:

Divide both sides by 13:

The formula for angle E:

Plug in the 8:

The angle measure of E is 42. So angle N is automatically 42 too.
To solidify, we can try to use the formula which they give us for angle N:
Answer:
D
Step-by-step explanation:
Differentiate the function and set it to zero:
f'(x) = -10x + 13
0 = -10x + 13
x = 1.3 seconds
Plug the x value into f(x):
f(1.3) = -5(1.3)^2 + 13(1.3) + 6 = 14.45 meters
Answer:
C
Step-by-step explanation:
If this was an equation...
(x-3)(x+5) = 0
x = 3, -5
So 3 and -5 are the minimum and the maximums.
So we convert that into an inequality.
-5 <= x <= 3
