Solve the equation for b. *
(50 Points)
12 = 6 (8) + b
Enter your math answer

B=-36

Step-by-step explanation:

First, do 6(8), which equals 48

The you subtract 48 from both sides, which leaves you with:

-36=B

b is equal to negative thirty-six.

Step-by-step explanation:

You can solve this by first multiplying the six and the eight.  Eight times six is equal to forty-eight.  You can then subtract that forty-eight from both sides, leaving you with the expression b = -36:

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
