Answer:
The area of triangle is 3444 mm².
Step-by-step explanation:
First, you have to convert the length of square into millimeters :
![1cm = 10mm](https://tex.z-dn.net/?f=1cm%20%3D%2010mm)
![8.2cm = 10mm \times 8.2](https://tex.z-dn.net/?f=8.2cm%20%3D%2010mm%20%5Ctimes%208.2)
![8.2cm = 82mm](https://tex.z-dn.net/?f=8.2cm%20%3D%2082mm)
Next, you have to apply area of square formula, A = length×height :
![area = length \times height](https://tex.z-dn.net/?f=area%20%3D%20length%20%5Ctimes%20height)
![let \: length = 82,height = 42](https://tex.z-dn.net/?f=let%20%5C%3A%20length%20%3D%2082%2Cheight%20%3D%2042)
![area = 82 \times 42](https://tex.z-dn.net/?f=area%20%3D%2082%20%5Ctimes%2042)
![area = 3444 {mm}^{2}](https://tex.z-dn.net/?f=area%20%3D%203444%20%7Bmm%7D%5E%7B2%7D%20)
Answer:
_ is equal to 28
Step-by-step explanation:
numerator is multiplied by 4, therefore, due to the equal sign, the denominator must also by multiplied by 4
The GCF of a polynomial is the greatest factor which is common to all the terms of the polynomial.
Thus, an example of a polynomial with a GCF of 7 is
The above polynomial can also be rewritten as
This form of the polynomial is obtained by factoring out the GCF of the polynomial.
I got 78.66, is there an answer choice like that?
