Simplifying algebraic expressions and distribution

Expand the expression and then simplify...

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

• 9x + 21

• 13x + 29

• 29x - 8

• 29x + 13

3 - 5(a - 4)

• 23 - 5a
• 5a - 23
• 18a
• -18a

What is the coefficient of y?

8 + 5x - y

• 8

• 0

• 1

• -1

-4(-4d - 5) 

• 16d+20
• -16d+20
• 16d-20
• -16d-20

Completely simplify both sides of the equation

2x - 3(5x - 1) = 4 + 2(3x - 5)

• 13x + 3 = 6x - 6

• -13x - 3 = 6x + 14

• 13x - 3 = 6x + 14

• -13x + 3 = 6x - 6

What is the constant in the following algebraic expression?

2x² + 3x - 6y - 9

• 6

• 9

• -9

• -6

Completely simplify both sides of the equation

4 - 5(x - 1) + x = 2x - 4(5x + 1)

• -4x + 9 = -18x - 4

• -6x + 9 = -18x - 4

• -4x + 9 = -18x + 4

• 6x + 9 = -18x + 4

Simplify the expression:
6 + 2(7x - 3) 

• 12 + 7x
• 14x
• 8x + 6
• 9 + 7x

Simplify:
-1x + y - z + 10z + 2x - 10y

• 1x - 9y + 9z
• 1x - 9z - 9y
• -1x - 9z - 9y
• -1x - 9 - 9y

5 less than the product of 7 and s

• 7s - 5
• 5 - 7 + s
• 7(s - 5) 
• 5 - 7s
