First, you would solve the parentheses.
72-(7+8)*4
72-(15)*4
Then, you would do multiplication.
72-60=
12
Hope this helps!
The answer is 12y^2 + 2y - 5
The solution:
(72y^3 + 12y^2 - 30y) / 6y =
(6y)*(12y^2 + 2y - 5) / 6y = 12y^2 + 2y - 5
I think it would be 90 because every triangle equals 180 and since it’s a right angel that’s 90 degrees for the square and 90+90=180
31/7 is the mixed number. I believe it can be the reciprocal as well.
