Dividing fractions is the same as multiplying by its reciprocal so you can change the equation to this

And you can simplify by eliminating the fours and multiplying straight across

You can pull out - 7 from the top and 2 from the bottom so you have this

And then you can cancel out to (2-x) to get an answer of
Answer:
baby, I don't know
Step-by-step explanation:
Answer:
width = let width be w
area = 140
length = 2w-6
Area of a rectangle = l*b
⇒ 2w-6*w=140
⇒ 
P = A(1+i)ⁿ, where:
A= initial value
I = interest in %
n= period of compound investment.
However, if the interest is paid twice a year, that means you have to divide the interest by 2 and the period becomes twice n
P = 875(1+9.5%/2)⁵ˣ²
P = 875(1+4.75%)¹⁰
P =875( 1.0475)¹⁰
P = $1,391.7
