D is going to be the correct answer.
Answer:
Step-by-step explanation:
we know that
The volume of a rectangular prism is equal to
-----> equation A
where
L is the length
W is the width
H is the height
we know that
-----> equation B
----> equation C
substitute equation B and equation C in equation A
Apply distributive property
Answer: The probability is 0.64
Step-by-step explanation: There are 39 counters in a bag. 14 of them are red and the remaining 25 are blue. Every time a counter is taken from the bag at random, there are altogether 39 possibilities regardless of the color of the counter drawn.
Also if we want to pick a blue counter from the whole lot, there are 25 possible chances.
Therefore the probability of picking a blue counter is shown as follows;
P(Blue) = Number of required outcomes ÷ Number of total possible outcomes
P(Blue) = 25/39
P(Blue) = 0.64
Therefore, the probability of taking a blue counter is 0.64 (or 64%)
Answer: x^3y^4 is the lowest common denominator.
Step-by-step explanation: To get both expressions to have a common denominator, multiply both of them to get them equal. For the first expression, multiply the numerator and denominator by y^3: 3y^3/x^3y^4
The second expression should be multiplied by the numerator and denominator by x^2: 7x^2/x^3y^4
(Add exponents when multiplying them) Now both expressions have common denominators.
Answer:x=4
Step-by-step explanation:
You can split this up into two equations
x-4=0
x+5=0
To solve each:
x-4=0
Add 4 to each side
x=4
------------
x+5=0
Subtract 5 from each side
x=-5
So your two solutions are -5 and 4 but you want the positive one so the answer is x=4
