Type the correct answer in each box.
an industrial laser cuts steel plates that are 11.93 meters long. the laser can have an error value of at most 0.02 meters.

the inequality |x −
| ≤
can be used to find the range of acceptable lengths for the steel plates.

the range of acceptable lengths for the steel plates is
≤ x ≤
.

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
