Answer:
3
days
Step-by-step explanation:
Let the amount of work be x.
Daniel:
10 days = x
1 day = 
x
Father:
6 days = x
1 day = 
x
Together:
1 day = x + x
= 
x + 
x
= 
x
= 
x
No. of days = 
x ÷ x
= x × 
x
=

"the product of" ⇒ ___ * ___
86 ⇒ 86 . . . . . fills first blank
and
the depth of the river ⇒ d . . . . . fills second blank.
Your expression is
86 * d
3(x^2+10x+5)-5(x-k)=
3x^2+30x+15-5x+5k=
3x^2+25x+15+5k
for this to be divisible by x every term must include x or get eliminated
the problematic terms are 15 and 5k
to eliminate them they must equal 0 when added:
15+5k=0
5k=-15
k=-3
so A) -3 is the solution
Answer:
yes
