Answer:
34 i think i got it really wrong but...
Step-by-step explanation:
Let, the integers = x,(x+1)
x*(x+1) = 56
x²+x = 56
x²+x-56 = 0
x²+8x-7x-56=0
x(x+8)-7(x+8)=0
x+8= 0 OR x-7=0
x = -8 OR x = 7
it would be -8 & -7 or 7 & 8
5 hours because 20 divided by 4 is 5. 20 being the total hours.
The answer is A. 3.79, -0.79
