Answer:
2y - 15
Step-by-step explanation:
well 15 LESS than TWICE a number. okay so let’s start off by making a variable for the unknown number.... y. the variable is y. so now we have to think, TWICE that number, but we don’t know the number.
Now that we have the variable and we know it has to be doubled, let’s start off making the first half... we can out that into 2y. which is 2 multiplied by the unknown number.
now that we have the first half done, we have to take the 15 less. Less can mean or subtract in this kind of situation. but for this certain scenario, it will be subtraction. so the equation would be 2y - 15.

The population refers to the whole set under study, while the sample is a representative part of that population.
Answer: B
Step-by-step explanation:
When you are multiplying exponents, if the base is the same, then you can directly add the exponents together.
We can see that both bases are 6. That means we can add the exponents.
[common denominator]
[add]
Now, we know that the answer will be 
.
We know that
area of lateral faces of the <span>right triangular prism=perimeter of base*height
perimeter of the base=[3+4+5]----> 12 cm
height of the prism=5 cm
so
</span>area of lateral faces of the right triangular prism=12 cm*5 cm---> 60 cm²
the answer is
60 cm²
