$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$3 x ^ { 2 } y - 9 x y ^ { 2 } + 12 x ^ { 3 } y ^ { 2 }$

Factor out $3$ .

$3\left(x^{2}y-3xy^{2}+4x^{3}y^{2}\right)$

Consider $x^{2}y-3xy^{2}+4x^{3}y^{2}$ . Factor out $xy$ .

$xy\left(x-3y+4x^{2}y\right)$

Rewrite the complete factored expression.

Kg to Pounds

8.3 kg in ponds is 18.26 lb

Kg to Ounces

8.3 kg in ounces is 292.16 oz

Step-by-step explanation:

We need to convert 8.3 kg to pounds and ounces

The conversion ratio is:

1 lb = 16 oz
1 kg = 2.2 lb

Converting kg to pounds(lb)

We know 1 kg = 2.2 lb

So, 8.3 kg = 8.3*2.2 lb

8.3 kg = 18.26 lb

So, 8.3 kg in ponds is 18.26 lb

Converting kg to ounces (oz)

We know that: 1 lb = 16 oz

We have converted 8.3 kg into 18.26 lb (pounds)

So, 1 lb = 16 oz

18.26 lb = 18.26*16 oz

18.26 lb =292.16 oz(ounces)

So, 8.3 kg in ounces is 292.16 oz

31. Algebra Fill in the reason that justifies each step.

Anna11 [10]

Answer:

Step-by-step explanation:

<u>Statements </u> <u> Reasons</u>

1) QS =42 Given

2) QR + RS = QS Segment Addition Postulate

3) (x + 3) + 2x = 42 Substitution Property

4) 3x + 3 = 42 Simplify

5) 3x = 39 Subtraction Property of Equality

6) x=13 Division Property of Equality

Explanation:

We have given QS=42. We have to prove that x=13

We will use Segment Addition Postulate which states that given 2 points Q and S, a third point R lies on the line segment QS if and only if the distances between the points satisfy the equation QR + RS = QS.

Then we will substitute the values in the defined postulate.

where QR= x+3

RS=2x

QS=42

QR+RS=QS

(x+3)+2x= 42

Now simplify the expression by opening the brackets.

x+3+2x=42

3x+3=42

Now subtract 3 from both sides.

3x+3-3=42-3

3x=39

divide both sides by 3.

3x/3 =39/3

x=13..
