Answer:

Polynomial equation is x²  - 16

Her pay if x = 12 is $128

Step-by-step explanation:

This week, Kyara worked x + 4 hours

She is paid x - 4 dollars per hour

She earned (x + 4)(x - 4) = x² - 16 dollars this week

Her pay if x - 12 is;

12² - 16 = $128

The goal of a toy drive is to donate more than 1000 toys. The toy drive already has collected 300 toys. How many more toys does
Brilliant_brown [7]

Answer:

Let t be the number of toys.

Since, the toy drive already has collected 300 toys

⇒ t+ 300

Also, it is given that the goal of a toy drive is to donate more than 1000 toys.

We get an inequality:

⇒t + 300 > 1000

Solve an inequality:  

t + 300 > 1000

Subtract 300 from both sides we get

t + 300 -300 > 1000-300

Simplify:

t > 700

Therefore, more than 700 toys does the toy drive need to meet its goal.

An inequality is; t + 300 > 1000 ;  t > 700
