Answer:
x =2
Step-by-step explanation: 9 + 3x = 15
-9 + 3x = -9

x = 2
the three other numbers are 2
Answer: 9/25 or 36%
Step-by-step explanation:
The first time it is a probability of 3/5, and the second blue also has a prbability of 3/5. Multiply them together since it is an "and" situation, and you get 9/25. Or, in percentages, it is 60% * 60%, or 0.6 * 0.6, which is 36% or 0.36. Hope this helps!
Hello :
by identity : (a-b)² = a² +b² -2ab
(x√7-3√8)(x√7-3√8) = (x√7-3√8)² = (x√7)²+(3√8)² -2(x√7)(3√8)
=7x²+72 -6x√56
= 7x²+72-6x√(14×4)
= 7x²+72-12x√(14).because :√(14×4)=2√14
Answer B
