</span>
-5y^3+7y^3-7y+8y+9 <---- Group like terms
-5y^3+7y^3+y+9 <---- Add similar elements
Answer: 2y^3+y+9
Read it carefully as it may look confusing with the symbols.
Answer:
y=39
Step-by-step explanation:
Remove the radical by raising each side to the index of the radical.
n, n + 2, n + 4 - three consecutive odd integers
366 - the sum
Equation:
n + (n + 2) + (n + 4) = 366
n + n + 2 + n + 4 = 366
3n + 6 = 366 |subtract 6 from both sides
3n = 360 |divide both sides by 3
n = 120
n + 2 = 120 + 2 = 122
n + 4 = 120 + 4 = 124
Answer: 120, 122, 124.
Step-by-step explanation:
(25x+8)°+(9x+2)°=180--->(1)(sum of angles on a straight line
(7y+5)°=(9x+2)°------------->(2)(vertical angles)
25x°+8°+9x°+2°=180°
34x°=170°
x=5°
from equation (2) substitute for x=5°
7y°+5°=9x°+2°
7y°+5°=9(5)°+2°
7y°=47°-5°
7y°=42°
y=6°
(x, y)=(5°,6°)
