Factorise 3(3x-y)-(y-3x)

snow_lady [41]

Answer:

4(3x-y)

Step-by-step explanation:

Given:

$\displaystyle \large{3(3x-y)-(y-3x)}$

To factor this kind of expression, first, find the common factor.

$\displaystyle \large{3(3x-y)-(-3x+y)}\\\displaystyle \large{3(3x-y)+(3x-y)}$

Notice that in the expression, we have both same (3x-y). Therefore, (3x-y) is our factor.

Let u = 3x-y

$\displaystyle \large{3u+u}\\\displaystyle \large{4u}$

Change u back to 3x-y:

$\displaystyle \large{4(3x-y)}$

Therefore, the factored expression is 4(3x-y).

D is the centroid of △ABC . What is the value of x when BD=2x+30 and BF=6x ?

EastWind [94]

Answer:

The value of x is $15\ units$

Step-by-step explanation:

we know that

The centroid is the point where all 3 medians intersect. The centroid divides each median in a ratio of 2:1

In this problem

$BD=\frac{2}{3}BF$

see the attached figure to better understand the problem

we have

$BD=2x+30$

$BF=6x$

substitute the values

$2x+30=\frac{2}{3}(6x)$

$2x+30=4x$

$4x-2x=30$

$2x=30$

$x=15\ units$
