Identify the Algebraic Expressions

Kendra’s math teacher assigned math homework, but Kendra decided to do 5 extra problems. Which algebraic expression shows how many problems Kendra completed?

• 5x

• x-5

• x+5

• x⁵

How many terms are in the given expression?
5² + 7n - 2f  

• 6

• 5

• 3

• 2

The sum of n and 9.

• n - 9

• n + 9

• n/9

• 9n

The product of 34 and z.

• 34/z

• z/34

• 34z

• 34 - z

Take 10 away from s.

• 10 - s

• s + 10

• s - 10

• s/10

Six times the number of girls.

Let g = number of girls.

• 6 + g

• 6g

• g - 6

• g⁶

d + d + d + d =

• d⁴

• 4d

• d4

• 4 + d

Multiply b by 6, then subtract 11.

• 6 x 11 - b

• 11 - 6 + b

• 6b - 11

• 11b - 6

Add 10 to b, then divide by 7.

• 10 x 7 / b

• (10 + b) / 7

• 10b / 7

• 10 + 7 / b

Simplify.

c + c + c + c + c + c

• 6c

• c⁶

• 6 + c

• 6 + c⁶
