Answer:
-914
Step-by-step explanation:
f(n)=-5f(n-1)-n
f(2)= -5f(1) -2 = -5(7) - 2 = -37
f(3) = -5f(2) - 3 = -5(-37) - 3 = 182
f(4) = -5f(3) - 4 = -5(182) - 4 = -914
4(.75) + 3
3 + 3

-------------------
6(.50) - 2
3 - 2

P = 2 (l + w)
P = 2(6 + 1)
P = 2 x 7
P = 14
<span>Length = x Width = 2x
Perimeter = 2 * length + 2 * width
= 2x + 4x
= 6x
6x = 66
x = 11
</span><span>Length = x Width = 2x
Perimeter = 2 * length + 2 * width
= 2x + 4x
= 6x
6x = 66
x = 11</span>

Angles in a triangle always add up to 180 degrees
Here, we add up all the angles given to equal it to 180 degrees:
X + X + 10 + X + 5 = 180
Collect like terms -> 3X + 10 + 5 = 180
Add the whole numbers -> 3X + 15 = 180
Take 15 from to the other side (then make it negative) to isolate the X:
3X = 180 - 15
The subtract -> 3X = 165
Take 3 over to the other side (and it it should divide 165) and isolate the X -> X = 165/3
Finally, X = 55
Now wherever you see X in the triangle, replace it with 55.
With that, the top angle = 55 + 10 = 65 degrees
The bottom left angle = 55 + 5 = 60 degrees
The bottom right angle = 55 degrees
