Answer:
A) 5x² - 6x + 1
Step-by-step explanation:
In this question, you would have to simplify the expression.
Solve:
(3x² - 2) + (2x² - 6x + 3)
Combine like terms.
3x² - 2 + 2x² - 6x + 3)
5x² - 2 - 6x + 3
5x² - 6x + 1
Since there's no more like terms, we have completely simplified the expression.
Therefore, your answer would be A) 5x² - 6x + 1
Answer: s=36
Step-by-step explanation:
To solve for s, we can use our algebraic properties to solve.
[subtract both sides by 14]

Answer:
60%
Step-by-step explanation:
Total number of people in the survey = 600
And 360 said their favorite was pepperoni.
Percentage of those who said pepperoni was their favorite will be
No. Of those who said their topping was pepperoni divided by the total number of people in the survey multiplied by 100%
That’s
360/600 x 100%
0.6 x 100%
60%
