Look at 3 on Variable B's axis, then go to the right until you reach the line.
After you reach the line, go all the way down and see what number you get to on Variable A's axis. You get 8, so that is your answer.
Use substitution
3x = 2(-6x + 18) + 14
3x = -12x + 36 + 14
3x = -12x + 50
15x = 50, x = 50/15 = 10/3
Solution: x = 10/3
The answer is 90, Because angle D is a 90 degree angle, and 180- 90=90, so the answer is 90.
Answer:
Odd
Step-by-step explanation:
One way I remember is that:
Even functions: Have symmetry over the y-axis
Odd functions: Don't have symmetry over the y-axis
The answer is: " 9a² + 7a " .

Note: (3a)² + 7a = (3a)*(3a) + 7a = 9a² + 7a .
