Answer:
8.3 cm
Step-by-step explanation:
So a pentagon has 5 equal sides, and the perimeter is the distance around a figure. Because we know the perimeter is 41.5 centimeters, we just divide that number by 5.
Perimeter (P) = s+s+s+s+s (sides)
P: 41.5 cm ÷ 5 =
8.3 cm
We know this is correct because:
8.3 + 8.3 + 8.3 + 8.3 + 8.3 = 41.5
Hope this helps!

Step-by-step explanation:
if A(-4;-7) and B(-2;-19), then the required slope can be calculated according to the next formula:

3,9,27 ( the 9 can be multiplied by itself to get 81 9*9)
Answer:
Step-by-step explanation:
100-29= 71
0.71 x $135=$95.85
$135 - $95.85= $39.15
$39.15 left, she spent $95.85
Answer:
Step-by-step explanation:
y = -12x - 1
y = 14x - 4
-12x - 1 = 14x - 4
-1 + 4 = 14x + 12x
3 = 26x
3/26 = x
y = 14x - 4
y = 14(3/26) - 4
y = 42/26 - 4
y = 42/26 - 104/26
y = - 62/26 reduces to - 31/13
solution : x = 3/26 and y = -31/13 or (3/26,-31/13)
