Answer:
Read below
Step-by-step explanation:
I would guess based on measurement because I would do the following.
3 1/4 x 3 1/4 = 10 9/16
10 9/16 x 3 = 31 11/16
Hope it helps c:
6s+4d=$53
4s+6d=$47
Multiply 6 in the first equation which is
36s+24d=$318
Multiply -4 in the second equation which is
-16s-24d=$-188
Then..
36s+24d=$318
-16s-24d=$-188
You cancel out the -24d and +24d
36s=$318
-16s=$-188
Do the math..
20s=$130
Divide 20 by both sides and answer...
s=$6.5
Right off the bat we know that the y-intercept is going to be 5 because of the second co-ordinate.
Now for the slope, because the y co-ordinate doesn't change, it has no slope so the equation is simply: y=5
Hope this helps :)
The formula is: a^2 h/3
the answer is about 0.49
