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
Answer:
x=40
Step-by-step explanation:
first you simplify both sides of the equation, then you isolate the variable
40/4= 10
10 times 3/2 = 15
If the car travels at the same speed for 12 hours the total miles will be 680.4
4/7 : 14
2 : 49

There are two acceptable ways of solving this. I'll show both (just in case one of them doesn't align with the information from your textbook).
Option 1 (fast and easy):The following is the equation for the area of a regular pentagon with side length s.

Plug s=12 into the equation.


The third choice should be your answer.
Option 2 (much more complicated):The area of a regular polygon can be solved with the following formula.

Let's solve for the apothem.
A pentagon can be divided into 5 congruent isosceles triangles. The vertex angle will be 360/5, or 72 degrees.
An isosceles triangle can be divided into two right triangles. One of the angles of the right triangle will be 72/2, or 36 degrees.
The leg opposite of the 36 degree angle will be 12/2, or 6 inches long.


The apothem is about 8.26 inches.
The perimeter is 12*5, or 60 inches.



(it seems that we're off by 0.1 due to rounding errors)
The answer is the third choice. Hope this helps! :)
