1 answer:
Answer:
Step-by-step explanation:
20. First find the values of the numbers being added.
These numbers have a common denominator, so you can add the numerators
27 + 25 = 52
so the number comes out to
to simplify, divide the numerator and denominator by 4.
So the final fraction becomes
However the question doesn't have this answer and now I am confused. I assumed that the expression was but the picture is a little bit blurry and I have bad eyesight so let me know if it is not. I'm too tired to delete this so next problem.
21.
4x + 8x + 7 + 4
Combine the like terms to get the expression
12x + 11 the answer is c.

because y^3 is raised to the power of two, we will have to multiply the exponents rather than adding them.
By distributing the power of 2, we will get y^2(6).
Because now the exponents are being multiplied, we can just add them to get y^8. The other y has a power of 1, so we'll just add the power of that y as well to get y^9.
summary:
multiply exponents if they are being raised to a power.
add exponents if they are being multiplied, and only add them if they have the same base (in this case, both the bases of the exponents are y, so we can add them)
By simplifying . This will result in a simplified version of
.
The Simplifying Algorithm is a wonderful way to simplify complex mathematics problems. It can be used to solve equations, convert fractions to decimals, and perform many other math operations. In this problem, the Simplifying Algorithm will help you reduce
Since two opposites add up to 0, remove them from the expression.
Write all numerators above the least common denominator 5x2
Use the commutative property to reorder the terms so that constants on the left
Rearrange the terms
By reording the terms
Hence, by simplifying this equation, divide both numerator and denominator. This will result in a simplified version of .
