Question 1
simplify the following expression: (5x2 + 3x + 4) − (2x2 − 6x + 3). if the final answer is written in the form ax2 + bx + c, what is the value of b?

question 2
simplify: (3x2 − 2) + (2x2 − 6x + 3)

5x2 − 6x + 1

5x2 − 6x − 1

x2− 6x + 1

5x2 − 8x + 3

question 3
a sports company conducted a road test of a new model of a geared bike. the test rider cycled (3x - 2) miles on a flat road, (x2 - 5) miles uphill, and (2x + 7) miles downhill. which simplified expression is equivalent to the total distance, in miles, for which the bike was tested?

x2 - x

x2 + 5x

x2 − x + 14

x2 + 5x + 14

question 4
simplify: (4x − 6) − (5x + 1)

x + 7

−x + 7

x − 7

−x − 7

question 5
simplify the following expression: (x + 6y) - (3x − 10y). if the final answer is written in the form ax + by, what is the value of a?

question 6
simplify: (3x − 5) + (3x + 6)

6x − 1

1

6x − 11

Question 1 Simplify the following expression: (5x2 + 3x + 4) − (2x2 − 6x + 3). If the final answer is written in the form Ax2 + Bx + C, what is the value of B?

Solution:

5x^2 + 3x + 4 - 2x^2 + 6x - 3 = 3x^2 + 9x + 1

Then, B = 9

Question 2
Simplify: (3x2 − 2) + (2x2 − 6x + 3)

5x2 − 6x + 1

5x2 − 6x − 1

x2− 6x + 1

5x2 − 8x + 3

Solution:

3x^2 - 2 + 2x^2 - 6x + 3 = 5x^2 - 6x + 1

Question 3
A sports company conducted a road test of a new model of a geared bike. The test rider cycled (3x - 2) miles on a flat road, (x2 - 5) miles uphill, and (2x + 7) miles downhill. Which simplified expression is equivalent to the total distance, in miles, for which the bike was tested?

x2 - x

x2 + 5x

x2 − x + 14

x2 + 5x + 14

(3x - 2) + (x2 - 5) + (2x + 7) = 3x - 2 + x^2 - 5 +2x + 7 = x^2 + 5x

Question 4
Simplify: (4x − 6) − (5x + 1)

x + 7

−x + 7

x − 7

−x − 7

(4x − 6) − (5x + 1) = 4x - 6 - 5x - 1 = -x -7

Question 5
Simplify the following expression: (x + 6y) - (3x − 10y). If the final answer is written in the form Ax + By, what is the value of A?

(x + 6y) - (3x − 10y) = x + 6y - 3x + 10y = -2x + 16y

A = -2

Question 6
Simplify: (3x − 5) + (3x + 6)

6x − 1

1

6x − 11

(3x − 5) + (3x + 6) = 3x - 5 + 3x + 6 = 6x + 1

Thats where they was ported and the fields that noone really knew much about needed tended, so they put slaves out there do free work and huge profits and so on the north decided to hold its own and was more different way of survival did not have same climate conditions to afford protecting slaves from winter so expenses be diff from south
