Given length l=7
width w=x-8
area=42
area=wl
42=7(x-8)
42=7x-56
7x=98
x=98/7
x=14
Answer: a, b, c, d
Step-by-step explanation: its not a fraction, its a integer, its positive, and is rational (every integer is rational).
Answer:
I don't know how to insert a number line, but you have to put on it x<-3. You have to plot it, then put a open circle at -3, and draw an arrow, pointing it farther into the negitive side of the number line.
Step-by-step explanation:
see picture for the graph
equation: y = 1.50x
now, keeping in mind that 1 degree has 60 minutes, and that 1 minute has 60 seconds and therefore there are 60*60 seconds in 1 degree, or 3600 seconds.
72°22'30", has 72 degrees, plus 22 minutes and 30 seconds.
or 72 degrees plus 22/60 degrees plus 30/3600 degrees.
