hello
to solve this question, let's try to write out an equation
Answer:
Step-by-step explanation:
To find which one is prime, let's try to factor them all. We can use the factoring by grouping method.
and
and
So this one is not prime, since you can still factor it.
and
and
So this one is not prime, since you can still factor it.
and
and
So this one is not prime, since you can still factor it.
and
and -x+2 cannot be further factored.
Therefore, is a prime.
It would be A that amy is 8 and billy is 14
Step-by-step explanation:
<h2>1).</h2>
The sum of interior angles of a polygon is given by
<h3>( n - 2) × 180°</h3>
where
n is the number of sides
From the question, the number of sides is 50 that's n = 50 .
Substitute the value into the above formula and solve.
We have
(50 - 2 ) × 180 = 48 × 180
<h3>The answer is 8640°</h3>
<h2>2).</h2>
The sum of interior angles of a polygon is given by
<h3>( n - 2) × 180°</h3>
where
n is the number of sides
From the question the sum of the angles is 2160°
Substitute the values into the above formula and solve for the number of sides.
That's
2160 = (n - 2) × 180
2160 = 180n - 360
180n = 2160 + 360
180n = 2520
Divide both sides by 180
n = 14
<h3>Therefore the number of sides is 14</h3>
<h2>3).</h2>
The exterior angle of a polygon can be found by using the formula
<h3>
</h3>
where
n is the number of sides
From the question the number of sides is 6 that's n = 6.
Substitute the value into the above formula and solve.
We have
<h3>
</h3>
We have the final answer as
<h2>60°</h2>
Hope this helps you.
