Without a vale to substitute for the variable, we can only simplify the expression: since
and
, the expression becomes

Now use the property 

Now we can factor
:

Answer:
X = 4/13
Y = - 5/13
Step-by-step explanation:
Since all of the equalities are true, the ordered pair is the solution of the system
Answer:
r=2.808cm h = 100cm
then we get volume of cylinder that is 2744 As explained below
Step-by-step explanation:
Volume of cylinder = πr²h
Surface area of cylinder = 2πrh +πr² (1)
h= 2744 /πr²
put value oh h in equation (1)
Area =[2πr] 2744 /πr²
=[5488/r +πr²]
dA/dx=0
i.e 2πr=5488/r²
Solving this r.r= ∛5488/2π
=2.808
taking second derivation we get 100
Answer:

Step-by-step explanation:
Answer:
The running club has 35 members
Step-by-step explanation:
Let
x ----> the total members of the running club
we know that
The total members of the running club multiplied by 5/7 plus 6 must be equal to 31 people
so

Solve for x




therefore
The running club has 35 members
