Answer:

The answer to your question is below

Step-by-step explanation:

2. $\sqrt{-128}$ Just find the prime factors of 128 and simplify

$\sqrt{-2^{7}} = \sqrt{-2^{6} 2} = 2^{3}i \sqrt{2}$

$8i\sqrt{2}$

3.- $\sqrt{-9} + \sqrt{-16}$ Get the square roots and simplify

3i + 4i

4.- None of the choices is equal to one, because the exponents are pair.

5.- 1/3x² + 10 = 7

1/3x² = 7 - 10

1/3x² = -3

x² = -3(3)

x² = -9

x = ±3i

What are the roots of the equation? x2−x−42=0 Enter your answers in the boxes.

Levart [38]

Answer:

x = 7 x = -6

Step-by-step explanation:

x^2−x−42=0

Factor

What two numbers multiply to -42 and add to -1

-7*6 = -42

-7+6 = -1

(x-7) (x+6) =0

Using the zero product property

x-7 =0 x+6 =0

x = 7 x = -6

Answer:

b=5

Step-by-step explanation:

We are going to use the basics of algebra to solve this

We need to isolate b by itself to find the value of b.

$8b + 12 = 52$

Subtract 12 from both sides

$8b = 40$

$b = 5$
