Answer:
A, C, E
Step-by-step explanation:
Angle x and the angle marked 63° are corresponding, hence congruent:
x = 63°
Angles x and z are consecutive interior angles, so are supplementary:
x + z = 180°
Then ...
z = 180° -x = 180° -63°
z = 117°
The conjecture is the formula, and we start with 3. However, as x increases, y decreases by 1, so we can do 3-x (as -1*x puts -x in)
5x(x+4)
Step by step
5x^2 = 5x(x) because it’s the largest you can divide by
20x =4 because 5x times by 4 = 20x
Which means 5x^2+20x = 5x^2+20x= 5x(x+4)
