Pepe's pizza makes 52 pizza crusts the first week and 180 pizza crusts each subsequent week. dianne's delicatessen makes 26 pizza crusts the first week and 90 pizza crusts each subsequent week. in how many weeks will the total number of pizza crusts made by pepe's pizza equal twice the total number of pizza crusts made by dianne's delicatessen?

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
