What number cubed equals -1331?
it is -11 because -11*-11*-11 equals to -1331
Answer:
The polygon has 9 sides
Step-by-step explanation:
we know that
A regular polygon has equal length sides and equal interior angles
step 1
Find the measure of the interior angle
Remember that
The interior angle plus the exterior angle must be equal to 180 degrees (form a linear pair)
Let
x ----> the measure of each interior angle in the regular polygon
so
solve for x
step 2
Find the number of sides of the regular polygon
we know that
The measure of each interior angle in a regular polygon is given by the formula
where
n is the number of sides of the polygon
substitute the given values
solve for n
therefore
The polygon has 9 sides

Answer:
x=3/8
Step-by-step explanation:
turn 3/4 into a fraction that has a denominator of 8 3/4x2= 6/8
To get it to 9/8 you add x which is 3/8
so 3/8+6/8 is 9/8
x=3/8
Answer: m = -1
Step-by-step explanation: In this problem we're asked to find the slope of the line that contains the points (-2,5) and (6,-3).
Using our slope formula, we take the <em>second y</em> minus <em>the first y</em> which in this case is -3 - 5 over our<em> second x </em>minus <em>our first x </em>which in this case is 6 - -2.
-3 - 5 simplifies to -8 and remember that minus a negative can be thought of as plus a positive so 6 - (-2) can be thought of as 6 + (+2) which is 8.
Now we have -8/8. Notice that our slope can be simplified one step further so we have <em>m = -1</em>.
The variable that's used to represent slope is <em>m</em>.
