Answer:

3 ( 64 x 2 y + 24 x '' − 8 r x y − 3 p x )

Step-by-step explanation:

If you're looking to factor, which is what I'm guessing you're trying to do. This will be your answer ^^.

If you're looking to factor by grouping: 3 ( 64 x 2 y +24 x '' − 8 r x y − 3 p x )

Glad I could help!!

In the diagram below, ABC~ DEC. What is the value of x?

pishuonlain [190]

The value of x will be 3

From given diagram, triangle ABC and EDC meet at a common vertex C.

So, triangle ABC and EDC both are congruent to each other.

Applying the similarity property of congruence, ratio of the congruent triangles' corresponding sides will be equal.

Therefore,

$\frac{AB}{ED} = \frac{AC}{EC} = \frac{BC}{CD}$

$\frac{AC}{EC} = \frac{BC}{CD}$

Simplifying the expression,

We get

(18-x)/x = 25/5

(18-x)/x = 5

18-x = 5x

18-x-5x = 0

18 - 6x = 0

- 6x = -18

x = 3

Hence, the value of x is 3.

3x + 4 = 8 To cancel + 4 from this equation you must do what?

Ratling [72]

You must subtract 4 onto the other side.
So...
3x = 4
To cancel a positive 4, you subtract to make it a negative :)
