Octagon:
= [(8-2)×180]÷8
= 135

Angle of LMN is:
= 360-135-60
= 165

Angle of EMN is:
= 180÷3
= 60

The number of side is :
[(n-2)×180]÷n = 165
(180n-360)÷n = 165
180n-360 = 165n
180n-165n = 360
15n = 360
n = 360÷15
n = 24

So, the number of side of the regular polygon R is 24.

Which expression is equivalent to (p^10r^−5)^1/5 ?

meriva

Answer:

p^2/r

Step-by-step explanation:

An equivalent expression is the expression in simplest form. Here apply exponent rules by multiplying the exponents of each term by 1/5.

$(p^{10}r^{-5})^{\frac{1}{5}}\\\\(p^{\frac{10}{5}}r^{\frac{-5}{5}})\\\\p^2r^{-1}\\\\\frac{p^2}{r}$

<u>Newton's Law of Motions</u>

Newton's 1st Law of Motion: An object at rest remains at rest and an object in motion stays in motion
Newton's 2nd Law of Motion: F = ma (Force is equal to [constant] mass times acceleration)
Newton's 3rd Law of Motion: For every action, there is an equal and opposite reaction<u> </u>

<h3>Step-by-step explanation:</h3>

<u>Step 1: Define</u>

[Given] F = 20.0 N

[Given] a = 5.0 m/s²

[Solve] Mass <em>m</em>

<em />

<u>Step 2: Solve for </u><em><u>m</u></em>

Substitute in variables [Newton's 2nd Law of Motion]: 20.0 N = m(5.0 m/s²)
[Division Property of Equality] Divide 5.0 on both sides: 4.00 kg = m
Rewrite: m = 4.00 kg
