To solve this problem you must apply the proccedure shown below:
1. The area of the rectangle is:
Where is the width and
is the length.
2. Based on the data given, solve for the width and then substitute the values of the length and the values of the area. Therefore, you have:
The answer is the second option:
Answer:
1 1/4
Step-by-step explanation:
five eighths plus five eighths equals ten eighths simplified to one and two eighths and simplified again to one and one fourth.
Answer:
Step-by-step explanation:
1) GCF = Greatest common factor which would be 6x so lets get started.
now we solve this with by quadratic formula.
so a=1 , b=6, c =8
and we get two values of x which is
but in the question it says we will end up with 3 solutions. Our third solution is actually
because we took 6x common as the greatest common factor so
so now we have 3 solutions
2) (x-9)(4x+1)=0
since this equation is already in root form we equate each root to 0
so our solutions are x=9 and x=-1/4
3)
now since we need to solve using square roots we apply square roots on both sides
since when we take the square root of a number we get positive and negative of that number example here
x+5=±12
so
x+5=12 and x+5=-12
x=7 and x=-17
4) Difference of two squares means we just need to factorize it in root form so lets begin,
now if we see this expression can be written like this as well
and if we expand this into the difference formula which is
we get
where a is 2x and b is 7
