Answer:
The area in factored form is 
.
The area in standard form is 
.
Step-by-step explanation:
The area of a rectangle is length times width.
So the area here is (x+2)(x-5).
They are probably not looking for A=(x+2)(x-5) because it requires too little work.
They probably want A in standard form instead of factored form.
Let's use foil:
First x(x)=x^2
Outer: x(-5)=-5x
Inner: 2(x)=2x
Last: 2(-5)=-10
---------------------Adding together: 
.
The area in factored form is .
The area in standard form is .
I did the problem and checked it on google and did the formula on paper. You would 628= 3.14 * x(squared) * 8, then you would undo everything, leaving you with x= 5
I tried my best, and I don't know if they wanted you to use pi or 3.14 so I hope this is correct :]
Answer:
1:4
Step-by-step explanation:
A ratio can be written like this: 15:60, but it can also be written as the fraction 15/60, which can be simplified to 1/4, or 1:4.
Answer:
A)(Always)Rational
B)(Always)Rational
C)(Sometimes)Rational
This is because Square roots are generally irrational(like the 
) and the product and difference of rational numbers should always be rational!
Hope this helps!
Sorry, cannot explain more ... :(
P.S. Stay Safe!
Answer:
7 hours and 30 minutes
Step-by-step explanation:
because if you divide the 5 hours by the 2 people you get 2 hours and 30 minutes so if you add one more person you are basically adding 2 hours and 30 minutes so if u add that 2 hours and 30 minutes to the 5 hours you will get 7 hours and 30 minutes
