Question

Three classmates are working with three different expressions. Each classmate substitutes in the value x=4
into their expression.

Kaleigh Hank Sonny
5x+7
5x2+7
5x+7
When substituting in the value x=4
, Kaleigh would get a result of
, Hank would get a result of
, and Sonny would get a result of
.



expression produced the largest value.​​​​​​

Answer 1

Let's evaluate each expression by substituting \( x = 4 \).

Kaleigh’s expression: \[ 5x + 7 = 5(4) + 7 = 20 + 7 = 27 \]

Hank’s expression: \[ 5x^2 + 7 = 5(4^2) + 7 = 5(16) + 7 = 80 + 7 = 87 \]

Sonny’s expression: \[ 5x + 7 = 5(4) + 7 = 20 + 7 = 27 \]

Now we summarize the results:

• Kaleigh's result: 27
• Hank's result: 87
• Sonny's result: 27

Among these results:

• Kaleigh: 27
• Hank: 87
• Sonny: 27

The expression that produced the largest value is Hank's expression, which resulted in 87.
