Answer:
12x + 30y square units
Step-by-step explanation:
Perform the indicated multiplication: 6(2x + 5y) = 12x + 30y square units
Probability=number of specific outcomes / total number of possible outcomes...
Since they want to know the probability of getting all of the colors the probability is just one.
The sum of all probabilities is always equal to one. In this case:
1/4+1/4+1/4+1/4=1
We know that the smaller base is x cm, the greater base is x+4 cm, and that the height is x/2 cm.
Since the area of a trapezium is given by

If we plug the expressions we have

If this must equal 84, we can solve for x as follows: start with

Multiply both sides by 4:

Subtract 336 from both sides:

We can divide both sides by 2 to make computation simpler:

Use the quadratic formula (or any mean you prefer) to solve this equation and get the solutions

We can't accept the negative solution, because it would imply

and we can't have negative side lengths. So, the answer is 12.
What is the range if this data set, 3,5,6,9,3,2,2,3,3,1

Answer:
8
Step-by-step explanation:
Subtract the minimum data value from the maximum data value to find the data range. In this case, the data range is 9-1=8.
Answer:
1. k + 2 (or other way around, it doesn't matter)
2. PY or P×Y
3. 10 - z
Step-by-step explanation:
1. You are adding here, so you add the two terms together.
2. If we had the amount of rulers and how much they cost, we could multiply to find these. Since we don't, we just leave the two variables to be multiplied.
3. It is asking the difference between two numbers, meaning that you need to subtract. With these types of problems, you always use the first number that appears in the problem to start the expression. For instance, if it had listed z first, then you would have done z - 10.
