You know from trigonometry that AB = 15 units, so the area of the larger triangle ACB is (1/2)*15*15 = 112.5 units^2.
Then the area of triangle ADE is
.. (112.5 -62.5) = 50 . . . . units^2
Opposite- 5/8
reciprocal- -8/5
absolute value- 5/8
6a³-18a²-1620a
Collect 6a:
6a(a²-3a-270)
6a(a-18)(a+15)
Answer:
31
Step-by-step explanation:
Lets say Friday papers are x
Saturday papers are 2x
Total cost of Friday papers are .75x
Total cost of Saturday papers are 3x
.75x+3x=116.25
3.75x=116.25
X=31
