A pizza shop sells a large and small pizza at discounted price every Thursday. The large pizza has 12 slices, a diameter of 15 inches, and cost $11.99. The small pizza has 8 slices, a radius of 4 inches, and cost $8.99. What is the area of the two pizzas? 1.) 33m2

2.) 153.9m2

3.) 103.6m2

4.) Non of the choices

the answer is a reflection across the line m

step-by-step explanation:

on edge

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

-2 is the right

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
