Simplify each expression
Citrus2011 [14]

Answer:

5x^4 + 15x^3 - 4x^2 + 7

Step-by-step explanation:

(7x^3 + 5x^4 + 3x^2) - (7x^2 - 7 -8x^3)

what we need to do is distribute the - sign in the middle of the parentheses into (7x^2 - 7 -8x^3)[/tex], this is very important to ensure we have the correct answer. by distributing we get the following equation:

7x^3 + 5x^4 + 3x^2 - 7x^2 + 7 + 8x^3

now we combine like terms to get our answer

5x^4 stays as it is, since there is nothing to combine it with

7x³ + 8x³ = 15x³

3x² - 7x² = -4x²

7 stays the same because like 5x^4, there is nothing else to combine it with

we have the following new equation:

5x^4 + 15x^3 - 4x^2 + 7

Simplify<br>10x - (5x-x)​
Alex17521 [72]

<em>Answer:</em>

<em></em>\boxed{6x}<em></em>

<em>Step-by-step explanation:</em>

<em></em>10x - (5x-x)<em></em>

<em>Distribute the Negative Sign:</em>

<em></em>= 10x + -1 (5x - x)<em></em>

<em></em>= 10x + -1 ( 5x) + -1 (-x)<em></em>

<em></em>= 10x + -5x + x<em></em>

<em>Combine Like Terms:</em>

<em></em>= 10x + -5x + x<em></em>

<em></em>= (10x + -5x + x)<em></em>

<em></em>= 6x<em></em>

<em>Hope this helped you!</em>

a mint plant grows 7/8 in 1 week and 13/16 inch the next week. use a common denominator to write an equivalent fraction for each
MAVERICK [17]

Answer:

28/32 and 26/32

Step-by-step explanation:

A common denominator of 8 and 16 is 32.

7/8 = (7 * 4)/(8 * 4) = 28/32

13/16 = (13 * 2)/(16 * 2) = 26/32

Two equivalent fractions with a common denominator are 28/32 and 26/32.
