Answer:
A) 1/(3x+1)
Step-by-step explanation:
(x+2)/(x³+2x²-9x-18)÷(3x+1)/(x²-9)
(x+2)/(x+2)(x+3)(x-3)÷(3x+1)/(x+3)(x-3)
since it’s dividing by a fraction, invert and multiply
(x+2)/(x+2)(x+3)(x-3) times (x+3)(x-3)/(3x+1)
The (x+2)’s cancel out.
The (x+3)’s cancel out.
The (x-3)’s cancel out.
You are left with 1/(3x+1)
A squared + b squared = c squared
8.6^2+14.7^2=c^2
73.96+216.09=c^2
square root both sides and...
c=17.03085
Your answer is A

Step-by-step explanation:
Answer:
9/64
Step-by-step explanation:
The probability that the marble on the first draw is blue is 3/8.
The probability that the marble on the second draw is blue is also 3/8.
So the probability that both are blue is:
3/8 × 3/8 = 9/64 ≈ 14%
When you graph an equation, it should be dependent variable against the independent variable. For this problem, the independent variable is the time, so this is along the x-axis. The dependent variable is d, so this is along the y-axis. Since the slope is Δy/Δx, then it is also equivalent to Δd/Δt. Therefore, the answer is B.
