You have the volume now you need to divide the numbers till you get the last number
This is a Pythagorean theorem problem. the ladder is 12 from the building and needs to teach 14 ft up. the length of the ladder it's the hypotenuse
12²+14²=c²
144+196=c²
340=c²
c=√340 or about 18.5 ft

Answer:
3(x^y(5x^2y-x³)+25x⁴))
Step-by-step explanation:
15x^2y²-3x^3y+75x⁴
From 15x^2y²-3x^3y only, 3x^y is the common factor
=> 3x^y(5x^2y-x³)+75x⁴
Taking the common factor of the latter expression, 3 shows to be the common factor of all the expression.
=> 3(x^y(5x^2y-x³)+25x⁴)
The best way to approach a word problem like this
is to break it down into pieces, so we can understand it fully.
In this problem, we have a number, which we don't know.
We can use any variable to represent it.
So let's use the variable <em>n</em> to represent it.
"Two less than three times a number" means 3n - 2.
A common mistake is for students to put 2 - 3n.
However, the word "less than" switches the order around.
So we have 3n - 2 = 19.
Solving from here, we add 2 to both sides to get 3n = 21.
Now divide both sides of the equation by 3 and we have n = 7.
So the number is 7.
