Answer:
145 candles
Step-by-step explanation:
Answer:
Approximately 19.4%
Step-by-step explanation:
Co. Dogs: 13
Co. Others: 54
13+54=Total Co.
=67.
Co. Dogs: 13/67.
App. 19.4% (For 13 Co.)
App. 1.49% (For 1 Co.)
7q² - 28 = 0
+ 28 + 28
7q² = 28
7 7
q² = 4
q = ±4
q = 4 or q = -4
Solution Set: {±4} and {q|q = 4 or q = -4}
I think you can solve it by
=(x^2 - y^2) *( x^2 + y^2)
= (x -y)*(x+y)*(x^2 + y^2)
