In AABC, point D is the centroid, and AD= 12. Find AG
Assoli18 [71]

Answer:

AG = 18

Step-by-step explanation:

The relationship of the segments created is one is 1/3 (shorter) and the other (longer) is 2/3 of the total length.

Lets make x represent AG.

So, 2/3 of x is 12

or

\frac{2}{3}x = 12

Multiply both sides by the reciprocal of \frac{2}{3} , which is \frac{3}{2}.

( \frac{3}{2}) \frac{2}{3}x = 12 (\frac{3}{2})  (x is left alone, the fractions = 1 when multiplied)

x = 12 (\frac{3}{2})         ( 12 times 3 = 36, divided by 2 = 18)    

x = 18

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).
