My drawing represents 37 - 19.
The red is the leftover when you subtract.
The blue is what you took away when subtracting.
I drew 37 red circles and then took away 19 circles by coloring them blue. You are left with 18 red circles.
The perimeter of a rectangle is - 2 x (length + breadth).
Also, 1 feet = 12 inches.
So, the dimensions of the tablecloth are 108 inches long by 72 inches wide. So, the total perimeter of the table cloth is --> 2 x (108 + 72) = 360 inches.
So, time taken for 1 tablecloth = 360 x 3 = 1080 minutes.
And, Time taken for 2 tablecloths = 1080 x 2 = 2160 minutes.
So, to complete her sewing project, Frances will take a total of 2160 minutes (36 hours).
With L` Hospital`s Rule ( ( tan x ) ` = 1/ cos^2 x ) :

Answer:
B & D
Step-by-step explanation:
The quadratic formula can be used to solve for x for any quadratic. Recall a quadratic is any function whose highest exponent known as degree is 2. Looking at the answer selections, A has one term with exponent 3. This isn't possible in the formula. Looking at answer C, the term with exponent 2 has the same coefficient on each side of the equal sign. When it is rearranged these will cancel out no exponent of 2 will be in the equation anymore. Only B & D work after being rearranged and simplified
