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:
≈ 1.8 km
Step-by-step explanation:
150*5= 750 revs total
d= 2.5 ft
C=πd= 2.5*3.14= 7.85 ft
Distance= 7.85*750= 5887.5 ft ≈ 1.8 km

Answer:
x=26
Step-by-step explanation:
The sum of all angles in a triangle is equal to 180
x + 55 + (4x-5) = 180
Combine like terms
5x +50 = 180
Subtract 50 from each side
5x +50-50 = 180-50
5x = 130
Divide each side by 5
5x/5 =130/5
x =26
