I believe the answer is A because you cannot find x nor y
V= Area of the circle at the base • height =
Pi•r^2 •h
x = 10
y = -2
z = -5
-x2 + 6zy = ???
Plug it in:
-(10)(2) + 6(-5)(-2) = ???
-10 x 2 + 6 x 10= ???
-20 + 60 = 40
Therefore, plugging the values in would make it equal 40.
Answer:
i don't know but i had it in my head but i cant remember it
Step-by-step explanation:
Step-by-step explanation:
1 is wrong, because if it says the sum of 5 times the number m and 12 that means its 5(m+12)=27
because its the sum and then 5 times that
2. You got the right answer, its five times x squared plus 2 is 22
