Which of the following is a solution of x2 + 4x + 10? (1 point) 2 + i times the square root of 6

−2 + i times the square root of 24

−2 + i times the square root of 6

2 + i times the square root of 24

9514 1404 393

  (c)  −2 + i times the square root of 6

Step-by-step explanation:

The quadratic can be rewritten as ...

  (x+2)² = -6

Taking square roots gives ...

  x +2 = ±i√6

Subtract 2 to give the values of x that are solutions.

  x = -2±i√6 . . . . . one of the roots is -2+i√6

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
