Answer:

a. 2.5

b. 2.333

c. 2.85

Step-by-step explanation:

A) 1. subtract -x on both sides 2. to get 3x-1/2=7

3. Add 1/2 on both sides 4. to get 3x=7.5

5. divide 3 on both sides 6. To get... x=2.5

B)1. Same process. 2. x+2=13/3

3. x=13/3-2 4. x= 2.33(repeating)

C) 1. same process. 2. 2x-x/3=3+7/4

3. 2x-x/3=4.75 4. Isolate -x/3

5.-x/3=4.75-2x 6. multiply both sides by 3

7. -x=14.25-6x 8. 5x=14.25

9. x= 2.85

* remember to distribute the 3 to each variable.

- What is the complete factorization of 4x2 – 24xy + 36y2 ?

Rzqust [24]

Answer:

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

Solution:

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)
