Answer: 81/2 inches squared or 40.5 inches squared
Step-by-step explanation:
The volume of a pyramid = bh/3
so V = bh/3
V = 108 and h = 8, so plug these in
108 = 8b/3
b = 108 *3/8
= 40.5 inches squared
or if you want a fraction, 81/2 inches squared
Do 6/30 and you will get .2lbs a day.
Answer:
-40
Step-by-step explanation:
Try rearranging and factoring -8y-2c-2b-8x-2a:
This is equal to -8(x + y) -2(a + b + c).
Since x + y = 7, we have:
-8(7) -2(a + b + c)
and since a + b + c = 8, we end up with:
-56 - 2(8), or
-56 - 16 = -40
