Exam 1

Add the polynomial (-3x + 4) + (8x - 5)

• 5x - 9

• 5x - 1

• 11x - 1

• 11x - 9

• None of these

(4x³-5x²+3x)+(-2x³-x²+6x)

• 2x³-6x²-9x

• 2x³+6x²+9x

• -2x³-6x²+9x

• 2x³-6x²+9x

• None of these

Add or Subtract to Simplify:
(4x²+ x) - (x²+ 2x)

• 3x² - x
• 4x² + 2x
• 3x² + 3x
• 3x² + 2x

Add or Subtract to Simplify:
(4n⁴ - 8n + 4) - (8n² + 4n⁴ + 1)

• -8n² - 8n + 3 
• -7n² - 8n + 3 
• -6n² - 8n + 3
• -7n² - 4n + 3

Solve for f:
S = 3f - 24

• f = (S + 24)/3
• f = (S + 24) - 3
• f = 3S + 24
• f = 3(S + 24)

Solve for x:
2x + 3y = 5

• x = (5 + 3y)/2
• x = 5 - 3y
• x = (5 - 3y)/2
• x = 5 + 3y

Solve the literal equation for the given variable.

• 2A/h
• 2/(h)
• 2Ah
• Ah/2

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

15 = 2a + 7

• 2
• 4
• 12
• 14

-15 = 5a +12- 2a + 6

• -11
• -3
• 10
• 7
