Answer:
C
Step-by-step explanation:
If you think about it hard enough, and look at it real hard, you can see. Think of like a capital L. 7 tall and 7 wide. I'm not sure but thats what I think.
Answer: ![\bold{-\dfrac{1}{2}}](https://tex.z-dn.net/?f=%5Cbold%7B-%5Cdfrac%7B1%7D%7B2%7D%7D)
<u>Step-by-step explanation:</u>
Average rate of change is the slope (m) between the two coordinates (-1, -1) and (1, -2).
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
![m = \dfrac{-2+1}{1+1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cdfrac%7B-2%2B1%7D%7B1%2B1%7D)
![=-\dfrac{1}{2}](https://tex.z-dn.net/?f=%3D-%5Cdfrac%7B1%7D%7B2%7D)
The area of a triangle could be determined using the following formula
![\boxed{a= \frac{1}{2} \times b \times h}](https://tex.z-dn.net/?f=%5Cboxed%7Ba%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20b%20%5Ctimes%20h%7D)
plug in the numbers
![a = \frac{1}{2} \times 21 \times 12](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%2021%20%5Ctimes%2012%20)
![a = \frac{1}{2} \times 252](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20252)
![a= \frac{252}{2}](https://tex.z-dn.net/?f=a%3D%20%5Cfrac%7B252%7D%7B2%7D%20)
a = 126
The area of the triangle is 126 square meters
Answer:
- leading coefficient: 2
- degree: 7
Step-by-step explanation:
The degree of a term with one variable is the exponent of the variable. The degrees of the terms (in the same order) are ...
6, 0, 7, 1
The highest-degree term is 2x^7. Its coefficient is the "leading" coefficient, because it appears first when the polynomial terms are written in decreasing order of their degree:
2x^7 -7x^6 -18x -4
The leading coefficient is 2; the degree is 7.

<em>Additional comment</em>
When a term has more than one variable, its degree is the sum of the exponents of the variables. The term xy, for example, is degree 2.
