Answer:
An estimate
Step-by-step explanation:
- 3x + 2x + 5 + 5x + 15 = 180 [angles on a line add to 180 degrees]
- 10x + 20 = 180 [combine like terms]
- 10x = 160 [subtract 20 from both sides]
- x = 16 [divide both sides by 10]
Arc AB measures 3(16) = 48 degrees.
Arc BC measures 2(16) + 5 = 41 degrees.
The answer to the question is -x-7
All of them seem pretty correct.
Also the answer to 12 is this...
Remove unnecessary parentheses
-6x2/3p^8x3
Then reduce the #’s with the greatest common divisor 3
-6x2p^8
Calculate the product
-12p^8
And that’s your answer:)))
