B
Vertex = (6,18)
Step-by-step explanation:
Vertex form = f(x) = a(x-h)^2+k
Answer:
16
Step-by-step explanation:
The angle shown there is an example of a vertical angle. An opposite angle formed by intercecting lines. They are always congruent, so to solve this, you must set them equal to eachother. you can gather the equation 4x-5=59. From there, you just solve it like you would any two step equation.
Answer:
B (i do also slightly lean towards C, but i'm pretty sure it would be B because it gives a specific measurement)
Step-by-step explanation:
If all angles that are either adjacent or opposite are supplementary, all angles must be 90°
If at all times adjacent sides are 5 inches, all sides are equal.
Knowing this, it has to be a square because all angles would be 90° and all sides would be equal.
Answer:
2n-8
Step-by-step explanation:
decreased means that you are subtracting the number in front from the other number therefore you get 2n-8
Its 60 all you really had to do is 6 times 10
