Answer:
1) -2x
2) 6x - 17
3) -16x
4) 3m - 5
5) 2m
6) 2x - 9
7) 9x
8) 6x + 8
Step-by-step explanation:
1) = x(7-9) = x(2) = 2x
2) x(-2+8) - 7 - 10 = x(6) - 17 = 6x - 17
3) x(-10-6) + 3 - 3 = x(-16) + 0 = 16x
4) m(2+1) - 6 + 1 = 3m - 5
5) m(10-8) = m(2) = 2m
6) x(1+1) - 5 - 4 = 2x - 9
7) x(4+5) = x(9) = 9x
8) x(7-1) + 3 + 5 = 6x + 8
Answer:
r = the square root of V/ pi*h
Step-by-step explanation:
You can find this by seperating r from the rest of the equation. You will have to divide V by pi and h, and then take the square root of it all, then r will be singled out on one side with the equation on the other. I added a picture so that it will be much more clear and simple.
(12+7x)(12-7x)
Because the square root of 144 is 12 and for 49 is 7
Answer:
Y=13
Step-by-step explanation:
X is 45 so
45+5y+5=9y-2 solve and y=13
m<CAE = 90: definition of perpendicular
p.s. ty for this!
