Answer:
-71-10n
Step-by-step explanation:
-4(11+4n)-3(-2n+9)
-44-16n+6n-27
-44-27-10n
-71-10n
Answer:
4
Step-by-step explanation:
the formula to calculate slope is
m=( y2-y1)/(x2-x1)
here,
(9,2)= x1 ,y1
(10,6)= x2 ,y2
putting the values in formula , we get
m= (6-2)/(10-9)
=4/1
= 4
Step-by-step explanation:
lets radius be r and height be h,
r+h=21 -----(1)
curved surface area
2×pi×r×h=616 -----(2)
use simultaneous eqn to solve for r and h.
total surface area of cylinder= 2×pi×r×h + 2×pi×r²
= ans if im not wrong
Answer:
D.
Step-by-step explanation:
f(5) = -25 + 40
f(5) = 15
We need to find m first.
m+n=12, n=5 (plug in n as 5)
m+5=12 (subtract both sides by 5)
m=7
m-n: we know that m is 7 and n is 5
7-5=2
The final answer is 2.
