5

Step-by-step explanation:

Well, if he mowed 13 total and 8 of them on Saturday you would solve like this:

13 - 8 = ?

13 (Total amount He Did)

8 (Amount he did on Saturday)

? (Amount he did on Sunday)

Which,

13 - 8 = 5

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

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
