<u>Answer: </u>

The complete factorization of 4 x^{2}-24 x y+36 y^{2} are 4(x-3y)(x+3y)

<u>Solution:</u>

Given Data:

4 x^{2}-24 x y+36 y^{2}

Take common value in all the three term.so we take 4 as common term in the above expression

4 x^{2}-24 x y+36 y^{2}=4\left(x^{2}-6 x y+9 y^{2}\right)

Now factorize the expression \left(x^{2}-6 x y+9 y^{2}\right)

Find the two numbers, whose product should be 9 and sum should be -6.

-3,-3 are the numbers which satisfy the above condition.

When we add -3-3=Sum is 6

Product of -3 \times -3= 9  

-3 , -3 satisfies the condition.

So the expression will become as x^{2}-6 x y+9 y^{2} = x^{2}-3 x y-3 x y+9 y^{2}

Take the common term

x(x-3y)+3y(x-3y)  

(x-3y)(x+3y)  

hence the complete factorization of 4 x^{2}-24 x y+36 y^{2} are 4(x-3y)(x+3y)

the number of grams a woman should eat in a day to maintain her weight is proportional to her weight. a woman weighing 102 pound
vitfil [10]
Given:
grams of fat : 34 grams TO weight of woman : 102 pounds
grams of fat : ? TO weight of woman : 180 pounds

This is a proportion problem: 34 grams to 102 pounds.

We first have to convert a unit of measure to another to maintain uniformity of measure. let us convert pounds to grams:

102 pounds * 453.592 grams / pound = 46,266.384 grams
180 pounds * 453.592 grams / pound = 81,646.560 grams

34 grams to 46,266.384 grams = x grams to 81,646.560 grams

proportion: a:b = c:d where ad = bc

34 grams * 81,646.560 grams = x * 46,266.384 grams
2,775,983.04 grams² = x * 46,266.384 grams
2,775,983.04 grams² ÷ 46,266.384 grams = x
60 grams = x 

A woman weighing 180 pounds should eat 60 grams of fat to maintain her weight.

A rectangular prism has a volume of 162 cubic centimeters. If the length, width, and height are reduced to 1/3 of their original
Colt1911 [192]
The original volume of the given prism is
l*w*h = 162
where l = length, w = width, h = height
Reducing 1/3 of each sides,
(1/3)l*(1/3)w*(1/3)h=(1/27)162
Thus,
The new volume is 162/27 = 6 cubic cm
