The final result should be 
.
In order to multiply any polynomials, use the pattern FOIL (which stands for first, outer, inner, last). You multiply what they ask you to at each step.
First - The first terms in both parenthesis.
Outer - The terms on the outside of both parenthesis.
Inner - The terms on the inside of both parenthesis.
Last - the last numbers in each parenthesis.
8 * - 5 = - 40
Now we put all the answers together and simplify like terms,
Answer:
Use the app photomath
Step-by-step explanation:
Answer:
9.07 and 7.77 respectively.
Step-by-step explanation:
To determine the upper control limit, add 0.65 lb to 8.42 lb, obtaining 9.07 lb.
To determine the lower one, subtract 0.65 lb from 8.42 lb, obtaining 7.77 lb.
Y - 4.5 = 12.2
your solving for y which means your trying to get rid of 4.5 so that y can equal something. The opposite of -4.5 would be +4.5, so you would add 4.5 to both sides to get
y = 16.7
So your answer would be
A. Add 4.5
and also dont' say your stupid because all you need is a little explanation and you'll get it, its very easy you just need to take the time to practice :-)
