What do you think what I have to do here because m confused The fraction 5/8 can be considered as the sum of 1/8 + 1/8+ 1/8 + 1/8 + 1/8 it can also be considered as the sum of 3/8+ 2/8 write two other ways to think of 5/8 as the sum.

1\8 and4\8

Step-by-step explanation:

1\8 + 4\8=5\8

where r the answers

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
