Answer:
Ravi’s present age will be 5.
Step-by-step explanation:
From the given, Let Ravi’s present age is taken as "a" years.
After 15 years, his age = (a+15) years.
By the given, it is identified that the age of Ravi after 15 years is equal to the 4 times of his present age.
Given,

Then, it has been found that the present age of Ravi is 5 when his age after 15 years will be 4 times of his present age.
Answer:
x^2 - 8x + 64 remainder 217 or you could write it as
(x^2 - 8x + 64)+ 217/(x + 8)
Step-by-step explanation:
You first need to write the polynomial in descending order of degree with zero coefficients for x^2 and x terms, so here we have:
x^3 + 729 = x^3 + 0x^2 + 0x + 729
So dividing by x+8:-
x^2 - 8x + 64 <----------the quotient.
x + 8 ) x^3 + 0x^2 + 0x + 729
x^3 + 8x^2
- 8x^2 + 0x
-8x^2 - 64x
64x + 729
64x + 512
217 = Remainder.

Answer:
2p(2+3q)
Step-by-step explanation:
Find the Greatest Common Factor (GCF).
GCF = 2p2p
Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
2p(4p/2p + 6qp/2p)
simplify each term in parentheses.
2p(2+3q)
Answer:
It is given that the volume of a cone =
cubic units
Volume of cone with radius 'r' and height 'h' = 
Equating the given volumes, we get

× 

It is given that the height is 'x' units.
Therefore, 

Therefore, 
So, the expression '
' represents the radius of the cone's base in units.
