Answer:
it should take her 45 minutes to run 9 laps
Step-by-step explanation:
40/8 = 5
9*5 = 45
(x-9) (x+2)=x²+2x-9x-18=x²-7x-18
The answer is 75 degrees I believe.
45 + 60 + x = 180
I’m pretty sure I’m correct but I’m so sorry if I’m wrong.
Answer:
65 degrees
Step-by-step explanation:
85 + 30 = 115
180 - 115 = 65
Verify:
a + b + c = 180
85 + 30 + 65 = 180
180 = 180
