Answer:

x = 2, x = -6

Step-by-step explanation:

x^2+4x-4=8

Subtract 8 from both sides.

x^2+4x-4-8=8-8

Simplify.

x^2+4x-12=0

Solve with quadratic formula.

a = 1

b = 4

c = -12

I do not have time to show work for quadratic formula parts.

I am so sorry for this inconvenience.

Korolek [52]

Answer:

x = 6

Step-by-step explanation:

4(x + 4) = 5(3 + 5) => Intersecting Secants Theorem

4(x + 4) = 5(8)

Open the bracket

4x + 16 = 40

Subtract 16 from each side

4x + 16 - 16 = 40 - 16

4x = 24

4x/4 = 24/4

x = 6

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

2x -1 > x + 2

Solve for x

Subtract x both sides

2x -1-x > x + 2-x

x-1 > 2

Adds 1 both sides

x-1 +1> 2+1

x> 3

The solution is the interval -------> (3,∞)

All real numbers greater than 3

In a number line is the shaded area at right of x=3 (open circle)
