What adds to -8 and multiplies to -20

2 answers:

4 0

I assume that you are talking about 2 integers
one of the integers must be negative while the other is positive
we can list integer pairs that multiply to -20:
-20 1
20 -1
-10 2
10 -2
5 -4
-5 4
now the only pair that when you add them together equals -8 is -10 and 2, so
-10 and 2 add to -8 and multiply to -20

Find the measure of one interior angle and

tia_tia [17]

Answer:

Part 1) For a octagon, the measure of one interior angle is 135 degrees and the measure of one exterior angle is 45 degrees

Part 2) For a icosagon, the measure of one interior angle is 162 degrees and the measure of one exterior angle is 18 degrees

Step-by-step explanation:

Part 1) we have a 8-gon

we know that

A 8-gon or octagon, Is an eight-sided polygon

step 1

The measure of one interior angle in a octagon is equal to

$\frac{180^o(n-2)}{n}$

where

n is the number of sides of the regular polygon

For n=8

$\frac{180^o(8-2)}{8}=135^o$

step 2

To find the value of a given exterior angle of a regular polygon, simply divide 360 by the number of sides

$\frac{360^o}{8} =45^o$

Part 2) we have a 20-gon

we know that

A 20-gon or icosagon, Is a twenty-sided polygon

step 1

The measure of one interior angle in a icosagon is equal to

$\frac{180^o(n-2)}{n}$

where

n is the number of sides of the regular polygon

For n=20

$\frac{180^o(20-2)}{20}=162^o$

step 2

To find the value of a given exterior angle of a regular polygon, simply divide 360 by the number of sides

$\frac{360^o}{20} =18^o$

Solve -6.5m+14.3<-22.75

Tom [10]

Step-by-step explanation:

-6.5m + 14.3 < -22.75

-6.5m < -37.05

6.5m > 37.05

m > 37.05/6.5 = 5.7

m > 5.7 for this inequality to be true

The equation of a circle is

sergij07 [2.7K]

Answer:

The answer is

<h3>center = ( - 7 , - 1)</h3><h3>radius = 6</h3>

Step-by-step explanation:

The general equation of a circle is given by

where the center of the center of the circle is given by

From the question the equation is

x² + y² + 14x + 2y + 14 = 0

Comparing with the general equation above we have

2g = 14 2f = 2

g = 7 f = 1 c = 14

So the center of the circle is

The radius of a circle is given by

$r = \sqrt{ {g}^{2} + {f}^{2} - c}$

where

g = 7

f = 1

c = 14

Substitute the values into the above formula

That's

$r = \sqrt{ {7}^{2} + {1}^{2} - 14 } \\ r = \sqrt{49 + 1 - 14} \\ r = \sqrt{36}$

we have the final answer as

<h3>radius = 6</h3>

Hope this helps you

Find the measure of ∠3.

Shkiper50 [21]

This is a kite due to the adjacent congruent sides (shown by the tickmarks). With any kite, the diagonals are perpendicular. So angle 3 is 90 degrees.

<h3>Answer: 90 degrees</h3>
