What means the same as 6 × 5? a.6^5 b.5 + 5 + 5 + 5 + 5 c.6 + 6 + 6 + 6 + 6

Here is your

In order to find your answer we will have to solve each option separately to see which one equals 6 × 5.

Therefore your answer is option C "6 + 6 + 6 + 6 + 6 ."

Hope this helps!

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

it is x equals 3   plese mark me really need it
