Answer:
8 interior angles
Step-by-step explanation:
- There is a simple trick to finding the number of interior angles
- For instance, a triangle has 3 sides, and how many angles are in a triangle? 3
- A square has 4 sides and 4 interior angles
- A pentagon has 5 sides and 5 interior angles
- So an octagon, the shape we have here, has 8 sides so 8 interior angles
Answer:
985.25
Step-by-step explanation:
An easy way to divide by larger numbers is to see if the divisor fits into the thousands, hundreds, tens, and ones place.
8 doesn't go into 7, so you'd bring down the number in the hundreds place and so on and so forth.

Answer:
a = 5, b = -3 and c =1
Step-by-step explanation:
The standard form of a quadratic equation is expressed as;
f(x) = ax² + bx + c
Given the expression
f(x) = 5x² = 3x - 1
f(x) = 5x² - 3x + 1
Comparing with the general formula;
ax² = 5x²
a = 5
bx = -3x
b = -3
c = 1
Hence a = 5, b = -3 and c =1
Answer:
See below
Step-by-step explanation:
I will describe this set in R³. Let P=(x,y,z) be a point equidistant to A and B, that is, the distance from P to A is equal to the distance from P to B.
First, using the usual distance formula, the distance from P to A is equal to 
On the other hand, the distance form P to B is equal to 
P is equidistant from A and B if and only if P satisfies the equation d(P,A)=d(P,B), that is,
Take the square in both sides of this equation to get
You can simplify using difference of squares and multiplying like this:
which is the equation of a plane.
