Answer:625
Step-by-step explanation:
Answer:
28 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180(n - 2) ← n is the number of sides
Here sum = 4680 , thus
180(n - 2) = 4680 ( divide both sides by 180 )
n - 2 = 26 ( add 2 to both sides )
n = 28
Answer:
C
Step-by-step explanation:
We know that the volume of a cylinder is given by the formula:
And we want to find the expression that represents the volume when the radius is (x+8) and the height is (2x+3).
So, let's substitute (x+8) for r and (2x+3) for h. This yields:
Let's expand.
Expand the square term first. We can use the perfect square trinomial pattern, which is:
Here, our a is x and b is 8. So:
Simplify:
Expand further. This time, we will use the distribute property. So:
Multiply:
Combine like terms:
Add:
Distribute the π:
So, our answer is C.
And we're done!
Answer:
D) 3
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Divisions
Additions
Subtractions

First, subtract 4 from both sides of the equation:
2x + 4 (-4) = 10 (-4)
2x = 10 - 4
2x = 6
Next, divide 2 from both sides of the equation:
(2x)/2 = (6)/2
x = 6/2
x = 3
D) 3 is your answer.
