Answer:


Step-by-step explanation:
so the question lets us know 3 things:
1) Sarah has a 27 ft pipe
2) she cuts 6 ft off
3) she cuts remaining pipe into 7 equal sections
what we don't know from the question is how big each of those 7 sections were. To form the equation we do this.
Since we know Sarah has 27 ft of pipe that would be our answer of the equation.
Sarah also removed 6 ft and the rest of the pipe she cut up into 7 small sections of equal length. since we don't know the length of the 7 smaller sections we will use the variable X to represent the length. this means that 6ft + 7x (X is the length of the pipes, and we multiply by 7 since there are 7 of them) must equal Sarah's total length of 27ft, therefore meaning our education would be

to solve for how long each pipe was, we need to solve for X by rearranging the equation as shown bellow.




Answer:
The least common multiple is 2y^2 - 50.
Step-by-step explanation:
Least common multiple means the lowest thing you can multiply them both to. For example, the LCM of 2 and 4 is 2, because 2*2 = 4 and 4*1 = 4.
First, factor 2y^2 - 50.
2 (y^2 - 25)
2 (y - 5)(y + 5)
Looks like if we wanted to get 2y^2 - 50 starting with y - 5, we'd have to multiply it by 2(y + 5).
2y^2 - 50 * 1 = 2y^2 - 50
y - 5 * 2(y + 5) = 2y^2 - 50
<u>So their least common multiple is 2y^2 - 50.</u>
