\qquad\qquad\huge\underline{{\sf Answer}}

Let's solve ~

\qquad \sf  \dashrightarrow \:  \dfrac{3 {x}^{2} y {}^{ - 1}}{27x  {}^{ - 3}  {y}^{8} }

Now, let's get the common terms out :

\qquad \sf  \dashrightarrow \:  \dfrac{3 {x}^{2} y {}^{ - 1}}{3 {x}^{2} {y}^{ - 1}(9 {x}^{ - 5} {y}^{9}    )}

cancel out the common terms in numerator and denominator

\qquad \sf  \dashrightarrow \:  \dfrac{1}{9 x  {}^{ - 5}  {y}^{9} }

\qquad \sf  \dashrightarrow \:  \dfrac{ {x}^{5} }{9   {}^{ }  {y}^{9} }

So, the correct choice is C

What is the minimum number of pieces of information you think you would need in order to prove that a given quadrilateral is a s
pashok25 [27]

Answer:

At least 4 numbers of information is needed

The four are highlighted below in the explanation section

Step-by-step explanation:

1. Given that the shape has four right angles and that all its sides are congruent then it's a quadrilateral

2. If two sides are consecutively congruent it is a quadrilateral shape

3. If a rhombus contains a right angle, then it’s a square shaped rhombus

4. If a quadrilateral is both a rectangle and a rhombus, then it’s a square

<span>From the problem, you can get this equation:
Jane is 2 years older than Sally
J=z+2
David is 4 times older than Jane.
D=4J

</span>Write two equivalent expressions that represent David’s age in terms of Sally’s age, z, and explain how the two expressions relate to one another.<span>Sally is z years old.
From the 2 equation above, you can get:
</span>D=4J
D=4(z+2)
D=4z+8

D-8=4z
(D-8)/4=z
The two equivalent expression would be D=4z+8 and (D-8)/4=z

The expression that more usefull would be D=4z+8 if you want to determine David age.

Please answer i need help please i will give you brainlest please
Shkiper50 [21]

Answer:

14) 4x+10=8x-26 (corresponding angles are equal)

4x-8x=-26-10

-4x=-36

x= -36/-4= 9

x=9

15) perimeter of rectangle= 2(l+b)

2( l+ \frac{2l}{3}) = 40m

2l+ \frac{4l}{3} =40

Take LCM as 3

\frac{2l}{1} * \frac{3}{3} + \frac{4l}{3} =40

\frac{6l+4l}{3} = 40

\frac{10l}{3} = 40

10l=40*3

10l = 120

l= 120/10 =12 cm

l=12cm

b= 2/3 *12 = 8cm

16) 2:3:4

It can be written as 2x+3x+4x

sum of angles of a triangle =180 degree

so 2x+3x+4x=180

9x=180

x=180/9=20 degree

1st angle=2x=2*20= 40 degree

2nd angle= 3x=3*20 =60 degree

3rd angle= 4x=4*20= 80 degree

17) sum of interior angles of a pentagon is 540 degree

so, 125+88+128+60+x=540 degree

401 +x= 540 degree

x=540-401= 139 degree
