81p²+90p+25=(9p)²+2*9p*5+5²=(9p+5)²
so the side length of the paining is 9p+5
Answer:
+-pi/3 and pi
Step-by-step explanation:

Squaring both sides:







Answer:
5/11
Step-by-step explanation:
Between numbers 1 - 11, the evens are 2, 4, 6, 8, and 10. Therefore, there are 5 evens.
Out of the eleven choices in the bag, there are 5 possible choices to be picked out of the 11 total choices.
Therefore, the probability of drawing an even number over the number of choices is 5/11.

According to this <em>trigonometric function</em>, −C gives you the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL.
