The best answer of multiplier is B
a^2+b^2=c^2
where c=25 m. and a=2b-10 m.
substitute
(2b-10)^2+b^2=25^2
4b^2-40b+100+b^2=625
5b^2-40b+100=625
divide both sides by 5
b^2-8b+20=125
subtract 20 from both sides
b^2-8b=105
complete the square
take half of 8 and square it=16

Answer:
x times 3 equals y
Step-by-step explanation:
If it doesn’t provide the amount of students, it needs to be written as an equation. x will be the amount of students and y would be the amount of pencils each person gets. So, you need to multiply x with 3 because then it will show the result, which is y.
