Maggie rectangle measures 2 1/3 units by 3 1/2 units . what is its area?

8.15 units²

Step-by-step explanation:

1, You can convert from mixed numbers to decimal numbers. Divide the numerator by the denominator of the fractional part and add it to the whole part, then:

2+0.33=2.33 units

3+0.5=3.5 units.

2. Then, you can calculate the area as following:

assuming you mean addition: addition and subtraction are reverse operations.

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
