The length of cell A is 6 x 10-6 m. The length of cell B is 0.0000002 m. What is the ratio of cell A's length to cell B's length? Use pencil and paper. Is it easier to find the
ratio when the numbers are expressed in scientific notation or in standard form? Explain your
reasoning

answer: 40.95

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

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
