The answer to the question is:

12x^6y^3z^3

You get this answer by doing:

2x^4yx=2x^5y You add 4x to 1x to get 5x.

Then rewrite the problem to get 2x^5y*<span>6xy^2z^3
</span>
Then to get the final answer multiply the equation.

1. Trapezoid KLMN has vertices K(1, 3) , L(3, 1) , M(3, 0) , and N(1, −2) .

chubhunter [2.5K]

Answer:

Step-by-step explanation:

(A) The vertices of the trapezoid KLMN are K(1, 3) , L(3, 1) , M(3, 0) , and N(1, −2)

Now, KL= $\sqrt{(3-1)^{2}+(1-3)^{2}}$ =\sqrt{8}[/tex]

LM= $\sqrt{(3-3)^{2}+(0-1)^{2}}=1$

MN= $\sqrt{(1-3)^{2}+(-2-0)^{2}}=\sqrt{8}$

NK= $\sqrt{(1-1)^{2}+(-2-3)^{2}}=5$

Now, as KL and MN are equal, therefore, KLMN is an isosceles trapezoid.

(B) Since m∠XWY=47°, therefore ∠XWZ=47+47=94° and ∠ZYW=18°, therefore ∠XYZ=36°( as diagonals bisect the angles)

In ΔXWO,

∠XWO+∠WXO+∠WOX=180°(Angle sum property)

∠WXO=43°

Also, from ΔXOY,

∠OXY=72° using the angle sum property.

Therefore, ∠WXY=43+72=115°

Now, sum of all the angles of a quadrilateral is equal to 360°, therefore

∠WXY+∠XYZ+∠YZW+∠ZWX=360°

115°+36°+∠YZW+94°=360°

∠YZW=115°

Therefore,∠WZY=115°

LetM be the mid point of AB, therefore M= $(\frac{-2+4}{2}, \frac{4+3}{2})$

= $(1,\frac{7}{2})$

Also, let N be the mid point of DC, therefore,

N= $(\frac{4-2}{2},\frac{-2-5}{2})$

= $(1,\frac{-7}{2})$

Now, length of the mid segment MN= $\sqrt{(1-1)^{2}+(\frac{7}{2}+\frac{7}{2})^{2}}=\sqrt{0+49}=7 cm$

(D)Given: Kite PQRS, TS=6cm and TP=8cm

Then, From triangle TSP, we have

$(SP)^{2}=(TS)^{2}+(TP)^{2}$

$(SP)^{2}=36+64$

$SP=10cm$

HELP ILL GIVE YOU BRAINLIEST

Alex Ar [27]

Answer:

1. Distributive Property

2. Addition Property of Equality

3. Multiplicative Property of Equality

Step-by-step explanation:

1. The 3 is multiplied by each number in the parenthesis

3*10=30

3*2=6

So 3*(10-2x)=30-6x

2. The 30 is subtracted from both sides

30-6x-30 = -6x

6-30 = -24

30-6x-30=6-30

So -6x=-24

3. The -6 is divided from both sides

-6x/-6 = x

-24/-6 = 4

-6x/-6 = -24/-6

So x=4

Please help me out with this question with explanation

Solnce55 [7]

Answer:

car covers distance of 450 km in 4hr and 30min

4hr and 30 min - (4*60)+ 30 equal to 270

distance covered by car in one minute equal to 450/270 equal to 1.6 km

speed of car equal to (1.6*60)/60 equal to 1.6 km /hr

Explain why f(x)=1/(x-3)^3 is not continuous at x=3

Bingel [31]

F(x)=1/(x-3)^3

The denominator can't be equal to zero (we can't divide by zero), then:
(x-3)^3 different 0
cubic root both sides:
cubic root [ (x-3)^3 ] different cubic root (0)
x-3 different 0
Adding 3 both sides:
x-3+3 different 0+3
x different 3

Then the function f is not defined at x=3

Answer: Option <span>b) f is not defined at x= 3</span>
