Because none of those are the right answer. you are given units in feet in the diagram. but are told 6 inches are lost in 4 hours. so you multiply length width and height keeping the feet then subtract .5 ft. the equation should look like V=(12×7×8)-.5
Answer:
x>-1

Step-by-step explanation:
(-4,-4) Answer) triangle vertex coordinates -4,8 | -1,5 | 5,5 orthocenter
X= first integer
21-x= second integer
(x)(21-x)= 108
multiply x by each term in parentheses
21x - x^2= 108
subtract 108 from both sides
21x - x^2 - 108= 0
-x^2 + 21x - 108= 0
multiply whole equation by -1 to eliminate the negative coefficient in the first term
(-1)(-x^2 + 21x - 108)= 0
x^2 - 21x + 108= 0
factor (remember we need #s to add to 21 and multiply to 108)
(x-12)(x-9)= 0
x-12= 0
x= 12
x-9= 0
x= 9
CHECK:
9 + 12= 21
9 * 12= 108
ANSWER: The two positive integers that add to 21 and multiply to 108 are 12 and 9.
Hope this helps! :)
