Answer: C

Step-by-step explanation:

Simplify to 4x^2 + 12x + 5 = 0 so that all the terms are on one side.

Do a part of the quadratic formula to see.

You only need to do the $-b^2-4ac$ part. If it is negative, that means there are irrational solutions. If it is positive, it has two solutions. If it is 0, it has 1 solution.

$12^2-4(4)(5) = 64$

It is positive so it has two solutions.

Answer:

Step-by-step explanation:

Corresponding angles equal 180 degrees when added

6x + 3x = 180

9x = 180

x = 20

angle CBD is 60 and angle GFH is 120

3(20) = 60

6(20) = 120

What is the answer to 5/3x + 4 = 2/3x

Alborosie

Answer:

5/3x + 4 = 2/3x

Step One- Subtract 5/3x to isolate the variable

4 = -3/3x

Step Two- Divide –3/3 to make your equation easier

4 = -x

Step Three- Divide by -1 (the lone negative cannot be there. It always represents a –1)

-4 = x is your answer!
