Answer:

Zhenghao is correct

Step-by-step explanation:

We have that:

(2x+3)(x + 4) = x² + 7x + 12

The only two factors of x² + 7x + 12 different from 1 ,-1 and and itself are (2x+3) and (x + 4)

If Hafsana says that (x + 3) is a factor of x² + 7 + 12, He or she is not correct.

If Zhenghao says that x² + 7x + 12 is divisible by 2x + 3, He or she is correct because (2x + 3) is a factor of x² + 7x + 12

A running back is having a great day on the football field. It’s only the third quarter, and he’s already rushed for 203 yards.

Naddik [55]

Answer:

He needs to gain more than 26 yards in order to break his record

Step-by-step explanation:

Let y stand for the number of yards he’ll have to gain. The sum of y plus the number of yards he already has (203) must be greater than 229 in order for him to break the record.

203 + y > 229 Set up the inequality.

203 − 203 + y > 229 − 203 Subtract 203 from both sides of the inequality.

y > 26
