Plz help brain fam!

What would make finding the answer a bit easier, is converting them into improper fractions. You would turn that first fraction to \frac{-9}{4} and the second fraction to \frac{-3}{2}. (You are dividing a negative by a negative, therefore, your answer would be a positive.

Let's follow the procedure of keeping, switching, and flipping. You keep the first improper fraction, switch the division sign to a multiplication sign, and flip the second fraction. That would make it : \frac{-9}{4} ×\frac{-2}{3}.

You multiply the 9 and the 2, you get 18. You multiply the 3 and the 4, you get 12. That makes it \frac{18}{12}. This, converted to a mixed fraction, makes 1\frac{6}{12}., which is the same as  1\frac{1}{2}. Your answer is the SECOND CHOICE.

Which expression is equivalent to (x^6y^8)^3/x^2y^2?
Masja [62]
For this case we have the following expression:
   (x ^ 6y ^ 8) ^ 3 / x ^ 2y ^ 2
 Rewriting and for power properties we have:
   (x ^ 18y ^ 24) / x ^ 2y ^ 2
   (x ^ (18-2) y ^ (24-2))
   (x ^ 16y ^ 22)
 Answer:
 
The equivalent expression is given by:
   (x ^ 16y ^ 22)

The length of Marshall's rectangular poster is 2 times its width. If the perimeter is 24 inches, what is the area of the poster?
Orlov [11]
Length=2x
width=x
Perimeter of a rectangle=2(length) + 2(width)
We can suggest this equation:
24=2(2x)+2x
24=4x+2x
24=6x
x=24/6
x=4

length=2x=2(4)=8
width=x=4

area of a rectangle=length x width
area of this poster (rectangle)=(8 in)( 4 in)=32 in².

The area of this poster will be: 32 in²
