To prevent the spread of flames caused by a grease spill, use a fire extinguisher or throw baking soda on the fire's .

True.

Explanation:

We already know that fire extinguishers are essential when it is necessary to prevent the spread of flames from a fire caused by a grease spill. What many people do not know is that in such cases throwing baking soda on the source of fire is also effective in preventing the spread of the flames.

Baking soda is the oldest type of chemical powder used against fires. It was widely used in commercial kitchens in the days when there were no damp chemicals like the saponifying agent Komet-K.

a, b, c - sides of a triangle

a + b > c

a + c > b

b + c > a

we have a = 5m and b = 11m. substitute:

5 + 11 > c

16 > c → c < 16

5 + c > 11         subtract 5 from both sides

c > 6

11 + c > 5         subtract 11 from both sides

c > -6

c < 16 and c > 6 and c > -6

thereofre your answer is 6m < c < 16m

the answer should be true
