Which expression represents the number
frozen [14]

Answer:

8 + i

Step-by-step explanation:

What you need to simplify this is the following "definitions" of i to different powers.

i^1=i

i^2=-1

i^3=i^2*i=-1*i=-i

i^4=1

Now we can sub these in for the various powers of i in our expression:

6(1)+6(-i)-2(-1)+\sqrt{-1*49}

Simplifying a bit:

6-6i+2+\sqrt{i^2*49}

Since we know that the square root of i-squared is i, and that the square root of 49 is 7, we can get rid of the radial sign as follows:

6 - 6i + 2 + 7i

And the final answer, in a + bi form, is

8 + i

Determine the correct set up for solving the equation using the quadratic formula.
netineya [11]

Answer: B

Begin by simplifying the given equation, so it's rearranged into standard form. Move all the terms onto one side, so they equal 0. This would result with 4x^{2}-3x-9=0. Quadratic formula is (-b±√(b²-4ac))/(2a). Standard form follow this variable format: ax^{2}+bx+c. Use the numbers that correspond with each variable to substitute them into the quadratic formula. This would be

(-(-3)±√(-3²-4(4)(-9)/2(4).
