Solve for x in the equation x2 + 2x + 1 = 17. O x=-11 15
O x=-14 17
O x=-2+2V5
O x=-1:13

x = sqrt(17) - 1 or x = -1 - sqrt(17)

Step-by-step explanation:

Solve for x:

x^2 + 2 x + 1 = 17

Hint: | Factor the left hand side.

Write the left hand side as a square:

(x + 1)^2 = 17

Hint: | Eliminate the exponent on the left hand side.

Take the square root of both sides:

x + 1 = sqrt(17) or x + 1 = -sqrt(17)

Hint: | Look at the first equation: Solve for x.

Subtract 1 from both sides:

x = sqrt(17) - 1 or x + 1 = -sqrt(17)

Hint: | Look at the second equation: Solve for x.

Subtract 1 from both sides:

 x = sqrt(17) - 1 or x = -1 - sqrt(17)

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
