The area of a rectangular rug is given by the trinomial r^2 - 8r - 33. What are the possible dimensions of the rug? Use factori

Arte-miy333 [17]

Solve for r using factoring:
Solve for r:
r^2 - 8 r - 33 = 0

The left hand side factors into a product with two terms:
(r - 11) (r + 3) = 0

Split into two equations:
r - 11 = 0 or r + 3 = 0

Add 11 to both sides:
r = 11 or r + 3 = 0

Subtract 3 from both sides:
Answer: r = 11 or r = -3

A- Veronica —> v=5+2m
Total —> v+m=32

B- since you already know that to get veronica’s number of stuffed animals, you need to use v=5+2m, you need to substitute it in the total equation. So it’ll be:

(5+2m)+m=32

(5+2m) represents veronica’s stuffed animals
m represents Mariposa’s stuffed animals

C- Mariposa —> 9
Veronica —> 23
