Answer:
I think its 38 however i could be wrong
Step-by-step explanation:
Self explanatory i just added them
**Put as brainliest if you wish**
(x - 9)(x + 9) would give you x^2 - 81 when you get a plus and minus like that after you factor the middle term is canceled out so the answer would be (x - 9)^2
Not sure about the last question
There's a lot of different approaches to this question, but the easiest one I see is this:
If a chord goes through the center of the circle, it is a diameter. That's 180 degrees we don't have to worry about. 47 is an inscribed angle, so we can multiply it by two to get 94 degrees. Subtract 94 from 180 to get 86.
See y? It's also an inscribed angle. To get it, we just take the 86 we just found for the remaining arc and divide by two.
The measure of y is 43.
It is not possible to divide by zero because if you do divide by zero, it will equal nothing, which means if you are sharing a pizza, no one gets anything.
