Let n be the no. of sides
(n-2)*180/n=156
180n-360=156n
24n=360
n=15
so the no. of sides is 15
Answer:
The are parallel lines.
Step-by-step explanation:
2x + 3y = 4
3y = -2x + 4
y = -2/3x + 4/3
10x + 15y = 2
15y = - 10x + 2
y = -10/15x + 2/15
y = - 2/3x + 2/15
The range and domain of the graph are the same. Both are all real numbers.
Answer:
Step-by-step explanation:
Let the length be L
Formula
SA = 2Lw + 2Lh + 2wh
Givens
h = 15 cm
w = 6 cm
L = ?
SA = 684 cm^2
Solution
Substitue what you know into the given formula
2*6*L + 2*15*L + 2 * 6 * 15 = 684 Combine
12*L + 30*L + 180 = 684 Combine again
42L + 180 = 684 Subtract 180 from both sides.
42L +180 -180 = 684 - 180
42L = 504 Divide by 42
Answer: L = 12
