Answer:
C. 52
Step-by-step explanation:
First, find the base of the triangle. You can do this by looking at the top of the figure. 14 inches is the width of the rectangle, and 20 inches is the width of the rectangle and the base of the triangle. You can find the base of the triangle by subtracting.

The base of the triangle is 6. The height of the triangle is equal to the height of the rectangle, 8. Now you need to find the hypotenuse of the triangle using the Pythagorean theorem:

c is the hypotenuse. Find c:

The hypotenuse of the triangle is 10. Now that you know the hypotenuse, you can find the perimeter. Add all the sides:

The perimeter is 52 inches.

Step-by-step explanation:
A polynomial is a sum of terms, each of which is the product of a constant and some constellation of variables to integer non-negative powers. Anything with a variable in a denominator, a non-linear function such as absolute value, or square root (a fractional power) will <em>not</em> be a polynomial.
The constants in a polynomial may be rational or irrational. The polynomials we generally study are ones with real coefficients, but there is no reason why the coefficients could not be complex numbers.

Answer:
- 8, 20, 32, 44, 56
- arithmetic
Step-by-step explanation:
The words "common difference" tell you this is an arithmetic sequence. A geometric sequence will have a <em>common ratio</em> between terms.
__
The common difference is added to each term to get the next.
first term: 8 -- given
second term: first term + common difference = 8 + 12 = 20
third term: 20 +12 = 32
fourth term: 32 +12 = 44
fifth term: 44 +12 = 56
The first 5 terms of this arithmetic sequence are 8, 20, 32, 44, 56.
y/x =k
13/9 = 1.4444444
39/27=1.4444444
104/72=1.4444444
k =13/9 = 1 4/9
this is direct variation with a constant of 13/9 or 1 4/9
