Explanation:
There are 4 quarts in one gallon.
This means that to convert quarts in to gallons, you just need to divide by 4.
8 divided by 4 is 2
So, there are 2 gallons in 8 quarts.
I= $75
500 x 5% x 3 years = 75
4/5 is the slope. When you isolate the y on one side of a linear equation, whatever number is with the x value is your slope.
First join the log4 on the left:
log4( x*(x-3) = log4(-7x+21)
Then x = -7, works: -7*(-10)=70 = -7*(-7)+21
x=-3, 18 = 42, does not work
x=3 0=0 works,
However, when one puts x = -7 in the *original* exression, log4(-7) or log4(-10) do not exist (you know why?). So x= -7 is extraneous.
Now x=3 gives log4(0) on the left and right, which does not exist.
So, C is the answer, both are extraneous. Seem to work but indeed don't work in the *original* equation
Answer:
B. 2340
Step-by-step explanation:
Interior angles of a polygon is given by
(n – 2)180 where n is the number of sides
(15-2) *180
13*180
