Answer:
8, 16, 64
Step-by-step explanation:
8 = 2^3 . . . a perfect cube
16 = 4^2 . . . a perfect square
32 = 2^5 . . . neither a cube nor a square
64 = 2^6 = 4^3 = 8^2 . . . both a perfect cube and a perfect square
128 = 2^7 . . . neither a cube nor a square
Answer:
This is a polynomial.
Step-by-step explanation:
A monomial is a constant, a variable or the product of constants and variables.
A binomial is the sum or difference of two monomials.
A trinomial is the sum or difference of three monomials.
Anything more than three terms makes it a polynomial.
This has 4 terms; thus it is a polynomial.

Answer:
a) He needs to consume 600 kcal from protein.
b) 22 kcal come from fat.
Step-by-step explanation:
a) Lee needs to consume 2400 kcal each day and 25% of this income should come from protein.
We are going to use percentages to solve this problem, to find out how many kcal from protein he should consume we need to multiply 2400 by .25.
2400 (.25) = 600
Lee needs to consume 600 kcal from protein.
b) A cup of chili contains 220 kcal If 15% of kcal come from fat how many kcal come from fat?
We are going to solve this in a similar way.
We should multiply the total amount of kcal by .15 which is the amount of fat calories.
220 (.15) = 33
33 kcal come from fat.
ANSWER
The correct answer is option B
EXPLANATION
The equations are
and
When we multiply the second equation by 
, we obtain;
When we combine this new equation with equation (1).
We can see that 
has been eliminated from the equation.
We can then, solve for 
and then substitute the result in to any of the equations to find .
Hence the correct answer is option B
