HELP ASAP! 10 POINTS Which expressions are equal to 8 × 10⁵ ? Select all that apply. A. 8 × 1 , 000 B. 8 × 10 , 000 C. 8 × 100 , 000 D. 8 × 10 × 10 × 10 × 10 E. 8 × 10 × 10 × 10 × 10 × 10

C and E

8 x 100,000 = 800,000

8 x 10 x 10 x 10 x 10 x 10 = 800,000

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

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
