I’ve had this question back when i was in school. Sorry for not explaining my work, in a bit of a hurry.
Hope this helps & good luck. :)
Is that the top or bottom? Assuming it's the top, when distributing the -2 to what's inside the parenthesis, they were correct in multiplying -2•7, but when they multiplied -2 and -y, the answer needs to be positive 2y because they are multiplying double negatives
Answer:
324 pi . and 36 pi
Step-by-step explanation:
Area is pi r squared, so 18x18 is 324, times pi which is 324 pi
Circumference is 2 pi r, which is 2 times 18 which is 36, times pi which is 36 pi
:D
The answer is 73
you just set it up at 73+91+x=79 and solve
