Answer:
(n+2)(n+1)
Step-by-step explanation:
Write out the numerator and cancel common factors:
(n+2)!/n! = (n+2)(n+1)n!/n! = (n+2)(n+1)
_____
You might be expected to multiply it out:
= n·n +2·n +n·1 +2·1
= n² +3n +2

The approximate mass of the spherical weight is 51 pounds
To answer the question, we need to know what the mass of the sphere is
<h3>Mass of the sphere</h3>
The mass of the sphere m = ρV where
- ρ = density of steel = 0.284 lb/in³ and
- V = volume of sphere = 4πr³/3 where
- r = radius of sphere = 3.5 in
So, m = ρV
= ρ4πr³/3
Substituting the values of the variables into the equation, we have
m = ρ4πr³/3
= 0.284 lb/in³ × 4π(3.5 in)³/3
= 0.284 lb/in³ × 4π × 42.875 in³/3
= 48.706π lb/3
= 153.014 lb/3
= 51 lb
The approximate mass of the spherical weight is 51 pounds

Answer:
Answer:
m=7
Step-by-step explanation:
1 blue jar = 16 marbles
1 blue jar = 2 red jars
Therefor
16 marbles= 2 red jars
(Now let m=1 red jar)
16= 2m
(Then sine we have 2m dived both sides by 2 to isolate the m)
16/2= 2m/2
8=m
