Answer:
p^(-9) or 1/p^9
Step-by-step explanation:
Here we have:
(5p)^(-7)
----------------
(20p)^2
Let's temporarily remove the coefficient 5/20 and reduce it to 1/4.
then we have:
1 1 1
(1/4) ------------- = (1/4) -------------- = ------------
p^7*p^2 p^(7 + 2) p^9

Answer:
obtuse triangle
Step-by-step explanation:
it is obtuse because it needs to have all 3 sides to be acute to be an acute angle and it doesn't have any 90° angles so it has to be obtuse. Also because to be an obtuse it has to have 2 acute angles and 1 obtuse angle. Hope this helps!!
Answer:
a) 44
b) 11
c) 4
Step-by-step explanation:
a) x + 46 = 90
x = 90 - 46
x = 44
b) 9x + 81 = 180
9x = 180 - 81
9x = 99
x = 11
c) (5x + 30) + 40 = 90
(5x + 30) = 90 - 40 = 50
5x + 30 = 50
5x = 50 - 30
5x = 20
x = 4
