Answer:

Step-by-step explanation:

a parallelogram has sides that are parallel to the opposite side. This means that y + 7 is going to be parallel to 20.

Two opposing sides of a parallelogram are parallel and equal

You know that the length of both of the sides is equivalent because the other set of opposing lines is also parallel (you can think of it as cutting off the line segment of y+7 and 20 at the same length. )

this means that we can set up the equation to find y as:

y + 7 = 20

then, you can proceed to find y by isolating it:

y + 7 = 20 ; so therefore

y + 7 = 20

- 7 -7

y = 13

So, the value of y is 13

Draw a regular pentagon so that it has a perimeter of 20 cm. Use the Regular Polygon Area Conjecture and a centimeter tyler to f

Ratling [72]

Answer:

Check the graph below. $Area = 27.52 cm^{2}$

Step-by-step explanation:

A Regular Pentagon has an interior angle of 108º an an exterior angle of 72º.

Since the perimeter is 20 cm, let's draw it respecting it those properties, besides all of the three sides must have the same measure.

And since we can divide it, into three triangles, we can calculate the area using tangent.

So, let's find out the area:

$A_5=\frac{s^{2}n}{4tan(\frac{180}{n})} =\frac{4^{2}*5}{4tan\frac{180}{5}}\\ \\A\approx27.52cm^{2}$

So check it down

Which value is equivalent to [(7x3x2)/(7x5)]^2 x [(7^0)x(5^-3)]^3 x 5^-9?

kaheart [24]

Answer: 36/25

Step-by-step explanation:

[(7x3x2)/(7x5)]^2 x [(7^0)x(5^-3)]^3 x 5^-9

= [(7x3x2)/(7x5)]^2 x [(7^0)x(5^3)]^3 x 5^-9

= [(7x3x2)/(7x5)]^2 x [1 x(5^3)]^3 x 5^-9

= [(7x3x2)/(7x5)]^2 x 5^9 x 5^-9

= [(7x3x2)/(7x5)]^2 x 5^0

= [(7x3x2)/(7x5)]^2 x 1

= [(7x3x2)/(7x5)]^2

= [(3x2)/(5)]^2

= [(6)/(5)]^2

= 36/25

Hope it helps.

Thank you !!
