Answer explanation

2(x+4)=50

Divide by 2.

x+4 = 25

Subtract 4 from both sides.

x = 21

2(x+4)=50

Distribute the 2 to (x+4)

2x+8=50

Subtract 8 from both sides.

2x = 42

Divide both sides by 2.

x=21

Match each expression to its factored form

• (3x-1)(2x+1)

• (x+3)²

• 2(x+3)(x-3)

• 3(x+2)²

Factor the following completely:

20x³ + 15x²

​ (a)   (​ (b)   )

• 5x²

• 4x + 3

• 15x

• 20x²

• 2x + 3

• 5x

• 4x² + 3

Match each polynomial to its factored form:

• (x-4)(x+1)

• (x+4)(x+1)

• (x-4)(x-1)

• (x+4)(x-1)

Factor:

5k³ + 7k² + k

• 5k(k² +2k + 1)

• 7k(5k² +k + 1)

• k(5k² + 7k + 1)

• 5k³ + 7k² + k

Factor each expression: 32m - 40

• 2(16m-20)

• 4(8m-10)

• 8(4m-5)

• none of those
