Problem: Hannah drew a rectangle on the whiteboard. The length was ⅚ inches and the area is 3 inches. What was the width of the rectangle? (Remember: Area = L x W) a. The answer to the problem as an improper fraction:

b. The answer to the problem as a mixed number

answer: 1 and 3

step-by-step explanation:

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

it has to have an angle of 90 degrees

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24
