Let's see what to do buddy...

- 3(4 - 2x) = 4 - 2x

Subtract the sides of the equation minus( 4 - 2x ) :

- 3(4 - 2x) - (4 - 2x) = 0

Factoring ( 4 - 2x ) :

(4 - 2x)( - 3 - 1) = 0

(4 - 2x)( - 4) = 0

Divided the sides of the equation by -4

4 - 2x = 0

Subtract the sides of the equation minus 4

- 2x =  - 4

Negatives simplified.

2x = 4

Divided the sides of the equation by 2

x =  \frac{4}{2} \\

x = 2

And we're done...

Thanks for watching buddy good luck.

How do I know if lines are perpendicular
AveGali [126]

You can tell if lines are perpendicular or not by seeing if meet in a right angle. A right angle is like a square, and the lines would have to be 90 degrees.

One example is when the two lines (horizontal and vertical) meet each other at the ends.

(You MUST make sure that they are directly horizontal and vertical. If not, they will either be acute or obtuse).

I hope this helped!

Consider the expression 40 + 24. Find the greatest common factor of the two numbers, and rewrite the expression using distributi
serg [7]

Answer:

40 + 24 = 8(5 + 3)

Step-by-step explanation:

Consider the expression 40 + 24. Find the greatest common factor of the two numbers, and rewrite the expression using distributive property

Step 1

We find the GCF

The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24

The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40

Then the greatest common factor is 8.

Step 2

Rewriting the expression using distributive property.

The factors of 40 and 24 that would give us the sum of 8 is given as 5 and 3

Therefore, using Distributive property

40 + 24 = 8(5 + 3)

Train A and train B leave a central station at the same time. They travel the same speed, but in opposite directions, with train
mylen [45]
Train A:

Distance (s) = 420 miles
Time (t) = 3 hours
Speed (v) = distance ÷ time = 420 ÷ 3 = 140 miles/hour

Train B: 

Distance (s) = 420 miles
Time (t) = 2.25 hours
Speed (v) = distance ÷ time = 420 ÷ 2.25 = 186.7 miles/hour

PLEASE ANSWER + BRAINLIEST!!
Gelneren [198K]
5x = x^2 + 4
x^2 - 5x + 4 = 0
(x - 4)(x - 1) = 0

x = 4, 1

(x + 6)^2 = 100
x + 6 = +/1 sqrt100
x + 6 = +/- 10

x =  4,  -16
