None because it is impossible for any triangle to have more than one obtuse angle.
No they wouldn't be the same because, the perimeter is adding all sides.
The square has 4 sides so you would add 9, four times.
9 + 9 + 9 + 9 = 36
And a pentagon has 5 sides so you would add 9, five times.
9 + 9 + 9 + 9 + 9 = 45
So, they are not the same.
Hope this helps. :)
Answer:
a=-0.5
Step-by-step explanation:
Distributive property for left side, difference of squares for right side.
8a-9a^2=-40+36-9a^2
-9a^2 cancels out
8a=-4
a=-0.5
(-x^2+4)
x^2y^3-2y^3-2x^2+4=x^2-2x^2+4=
(-x^2+4)
40*52= 2080
34840 / 2080 = $16.75 an hour
