Which expression is equivalent to 4x+20?
max2010maxim [7]

Answer:

4x+20=

6x-10

Step-by-step explanation:

Simplifying: 4x + 20 = 6x + -10

Reorder the terms: 20 + 4x = 6x + -10

Reorder the terms: 20 + 4x = -10 + 6x

Solving: 20 + 4x = -10 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation: 20 + 4x + -6x = -10 + 6x + -6x

Combine like terms: 4x + -6x = -2x: 20 + -2x = -10 + 6x + -6x

Combine like terms: 6x + -6x = 0: 20 + -2x = -10 + 0: 20 + -2x = -10

Add '-20' to each side of the equation: 20 + -20 + -2x = -10 + -20

Combine like terms: 20 + -20 = 0: 0 + -2x = -10 + -20: -2x = -10 + -20

Combine like terms: -10 + -20 = -30: -2x = -30

Divide each side by '-2': x = 15

Simplifying: x = 15

Answer:

(2x-3) (2x+3)

zeros, x intercepts:  -3/2, 3/2

Step-by-step explanation:

4x^2 -9

We know the difference of squares is a^2 -b^2

This factors into (a-b) (a+b)

Let 4x^2 =a^2  

Taking the square root

2x =a

Let b^2 =9

Taking the square root

b= 3

(4x^2-9 ) = (2x-3) (2x+3)

To find the zeros, we set the equation equal to zero

(4x^2-9 ) = (2x-3) (2x+3) =0

Using the zero product property

2x-3 =0   and 2x+3 =0

2x-3+3 = 0+3                    2x+3-3 = 0-3

2x=3                                  2x=-3

Divide by 2

2x/2 = 3/2                               2x/2 = -3/2

x = 3/2                                       x = -3/2

These are the zeros of the equation (which are also the x intercepts)

3 x 7= 21

3 x 7= 21

2 x 3= 6

2 x 3= 6
