Please help I’m confused

You have to plug in each value of x in order to get the value of y, then write each as an ordered pair.

Step-by-step explanation:

3x + 4y = 12

3(-2) + 4y = 12

-6 + 4y =12

4y = 18

y = 18/4 = 9/2 ordered pair: (-2, 9/2)

3(0) +4y = 12

4y = 12

y = 3 ordered pair: (0, 3)

3(2) +4y =12

6 + 4y = 12

4y = 6

y = 3/2 ordered pair: (2, 3/2)

3(4) + 4y = 12

12 + 4y = 12

4y = 0

y = 0 ordered pair: (4,0)

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
