Answer:
50
Step-by-step explanation:
Because of supplementary angles that line has to equal to 180
180-75 = 105
so 105 = (2x + 5)
you can subtract 5 from each side and get
100 = (2x)
then divide each side by 2 and you get
x = 50
you can check it by doing (2 x 50 + 5)
2 x 50 = 100 + 5 = 105 + 75 = 180
Answer:
B. (x - 8)(x - 5)
Step-by-step explanation:
If you plugged in x = 5 into the 2nd equation, you would see that you would be multiplying by 0, which would turn everything zero.
