Answer:
(x+1)(x+20)
Step-by-step explanation:
1) find two factors of 20 that sum up to 21.
2) 1 and 20 are two facts of 20 that sum up to 21.
An exterior angle of a triangle is the sum of both of its opposite angles so 60 + 60 = 120 and 120 * 3 = 360
your answer is 360 degrees.
The expression that determines the volume of the container is 
<h3>How to determine the volume expression?</h3>
The given parameters are:
- Shape = Cone
- Height, h = 9 in
- Diameter, d = 4 in
The volume of the cone is calculated using:

So, we have:

This gives

Hence, the expression that determines the volume of the container is

Answer: B. it is a binomial with a degree of 3
<u>Step-by-step explanation:</u>
3xy² + 5x²y
There are two terms so it is a BINOMIAL
xy² has a degree of 1 + 2 = 3
x²y has a degree of 2 + 1 = 3
The largest sum of exponents in a term is three so DEGREE is 3
<span>FV = PV × (1+r)^n ; </span><span>where FV = Future Value;
PV = Present Value;
r = annual interest rate;
n = number of periods;
FV = 1260 </span>× 1.085^6 = 1260 × 1.63 ≈ 2054 ;
