Answer:
z = 2.7x/r²y
Step-by-step explanation:
z = kx/r²y
½ = k × ⅓ ÷ (3² × ⅕)
½ = ⅓k × 5/9
k = 27/10 = 2.7
z = 27x/10r²y
z = 2.7x/r²y
You gave no options but the simplest way to solve this is to set it equal to all of the answers to see if it is correct.
(-x-1)(x-1)(x^2+6)
distribute from there i think?
math papa website can help with this... im not that good at math
