Answer:
not 100% confident but I think this is at least close
Step-by-step explanation:
solve for one variable
1. x-5y=2
x=2+5y
plug this in to another equations and simplify
2. (2+5y)-y=16
2+4y=16
4y=14
y=3.5
this can be plugged in to all other equations to find x
1. x-5(3.5)=2
x-17.5=2
x=19.5
2. x-(3.5)=16
x=19.5
3. 2x-(3.5)=5
2x=8.5
x=4.25
4. x-3(3.5)=4
x-10.5=4
x=14.5
I believe the answer would be a(a-4)(a-13)
I started with the a^3 - 17a^2 + 52a and factored out an "a"
---> a(a^2 - 17a +52)
Then I factored the expression in parentheses (*To factor it, you need to find out what multiplies to become 52 and adds to become 17*) And you get -4 and -13
---> a(a-4)(a-13)
