Answer:
A number used to multiply a variable. Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient. Variables with no number have a coefficient of 1.

Answer:
Angle 1=180-(75+30)=180-105=75
angle 4=angle 1+angle angle 2=150
Step-by-step explanation:
You know that the segment is rotated at a 90 degree angle.
As seen, the segment is in quadrant one and two.
For a':
a(3, 1) --> (-3, -1)
For b':
b(-1, 1) --> (1, -1)
As you can see, the coordinate's signs are reversed for each case.
Hope I helped :)
4(2d + 5) = 8d + 20
15x + 18y = 3(5x + 6y)
