-- Every triangle has three (3) sides and three angles.
If it doesn't, then it's not a triangle.
-- A triangle <em><u>can</u></em> have one right angle, and no more than one. But it
doesn't need to have one, and triangles don't always have one.
-- A triangle <em><u>never</u></em> has any parallel sides.
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- 4x + 8y = 20
- -4x + 2y = -30
<u>Adding</u><u> the</u><u> equations</u><u> </u><u>:</u><u>-</u><u> </u>
10y = -10
y = -1
<u>Put </u><u>it </u><u>(</u><u>i)</u><u> </u><u>:</u><u>-</u><u> </u>
4x - 8 = 20
4x = 20 + 8
4x = 28
x = 28/4
x = 7
He starts with 10, +5 after every week
week 2=10+5
week 3=10+5*2
...
week 25 =10+5*24
f(x)=10+5(x-1)
so during the 25th week=10+5*24=10+120=130
