I'm sorry I don't know but you can use photomath you can just download it from the App
Just answering for a task
8p-8=-9(2p+5)-9(6-3p)
p=91
I showed the work up there and checked
D.
f(x) can be written as (x+2)(x-2)(x-1)
by using difference of two squares to expand x^2 - 4 whch yields 3 x intercepts
similarly, k(x) can be written as
x(x+5)(x-5) which also yields 3
x intercepts (0,-5, and 5)
