I don’t think any of them are right
All the corners of a rectangle is equal to 90 degrees. So you need to set (x-1) and (2x+10) equal to 90 and then solve for x.
(x - 1) + (2x + 10) = 90
<em>Combine the like terms...
</em>3x + 9 = 90
<em>Subtract both sides by 9...
</em>3x + 9 - 9 = 90 - 9
3x = 81
<em>Divide both sides by 3...
</em><em>3x = 81
</em>(3x) / 3 = 81 / 3
x = 27
Hello from MrBillDoesMath!
Answer:
a(n) = 12 - 3(n-1) , n = 1,2,3.,,
Discussion:
The terms are 12, 9, 6, 3 so we are apparently subtracting 3 from each succeeding term. . Hence
a(n) = 12 - 3(n-1) , n = 1,2,3.,,
Thank you,
MrB
Answer:
I don’t know how to help you with that because I don’t have your math journal. And stander form of what exactly?
The answer it’s y=2.54x I just did the assignment
