To find the measure of the interior angles, we know that the sum of all the angles is 900 degrees (from above)... And there are seven angles... So, the measure of the interior angle of a regular heptagon is about 128.57 degrees.
Use order of operations to simplify the expression.
![(5n \times 9) \times 2n](https://tex.z-dn.net/?f=%285n%20%5Ctimes%209%29%20%5Ctimes%202n)
![(5n \times 9) = 45n](https://tex.z-dn.net/?f=%285n%20%5Ctimes%209%29%20%3D%2045n)
![(45n) \times 2n = {90n}^{2}](https://tex.z-dn.net/?f=%2845n%29%20%5Ctimes%202n%20%3D%20%7B90n%7D%5E%7B2%7D%20)
Answer is
![{90n}^{2}](https://tex.z-dn.net/?f=%20%7B90n%7D%5E%7B2%7D%20)

The correct answers are 2h-2=92 and h-2=92-h.
Explanation:
Hannah, h, is the older sibling and their ages are consecutive odd integers. This means that Anthony's age will be 2 less than Hannah's, or h-2.
The sum of these would be h+(h-2), giving us the equation h+(h-2)=92.
Combining like terms we would have the first correct choice, 2h-2=92.
Our first equation can be transformed, however, to have (h-2) by itself. To do this, we would subtract h from both sides, giving us h-2=92-h.
Hope this helps!
Answer:
5*7
Step-by-step explanation:
5 is prime because it has only 2 factors: 1 and itself.
7 is prime because it has only 2 factors: 1 and itself.
I hope it helps you!:-)
The distributive property states that a(b+c)=ab+ac.
In this situation, 4(x+2)= 4*x+ 4*2.
While the student multiplied 4*2 to get 8, the student did not multiply 4*x to get 4x.
