Cynthia Besch wants to buy a rug for a room that is 26 ft wide and 35 ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 682 square feet of carpeting. What dimensions
should the rug have?

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
