Answer:
13in
Step-by-step explanation:
Let the width be w
The length will be 8+w
(8+w)(w)=65
8w+w^2=65
w^2+8w-65
Use quadratic equation formula.
You will get two answers
w=5 or w= -13
Pick the answer that is more sensible.
It cannot be a negative number; hence use 5in
5in+8in= 13in
Answer:
√ (p(1-p) / n)
Step-by-step explanation:

To find the magnitude of a vector, take the components, square them, then add them, then take the square root. This is very similar to the Pythagorean Theorem.
For your particular problem, I’ve included a picture showing how that specific calculation is done. :)
No they don't have enough, they need 1/4 more cups of flour
