Answer:

x² -22 = 0

Step-by-step explanation:

The roots are opposites, so the equation is pretty simple.

x² = 22 . . . . . square both sides

x² -22 = 0 . . . . your quadratic equation in standard form

P=2L +2W;P=32,W=7 25 16 12.5 9

Marianna [84]

Answer:

L = 9

Step-by-step explanation:

Assuming you are trying to find L

P = 2L + 2W

P = 32

32 = 2L + 2W

W = 7

32 = 2L + (2 × 7)

32 = 2L + 14

2L = 32 - 14

2L = 18

L = 9

What is −30−6r= -36 ?

Nadya [2.5K]

-30-6r=36

We move all terms to the left:

-30-6r-(36)=0

We add all the numbers together, and all the variables

-6r-66=0

We move all terms containing r to the left, all other terms to the right

-6r=66

r=66/-6

r=-11
