Foil the binomials
First: n*n=n^2
Outer: n*-5=-5n
Inner: -3*n=-3n
Last: -3*-5=15
Put it together and simplify
n^2-5n-3n+15
n^2-8n+15
Final answer: A
Step-by-step explanation:
Now subtract.....
hence the answer is 3 ....
hope it helped !!!!
The unit rate of the proportional relationship y = 3x is 3
<h3>How to determine the unit rate?</h3>
The proportional relationship is given as:
y = 3x
Divide both sides by x
y/x = 3
For a proportional relationship y/x = k;
The unit rate is 3
This means that the unit rate of the proportional relationship y = 3x is 3
