What are the solutions to m^2 – 9 = 0?

m = –9 and m = 0
m = –3 and m = 3
m = –3
m = 9

The value of the m is the equation m² - 9 = 0 are + 3 or - 3 .

Step-by-step explanation:

As given the expression in the question be as follow.

m² - 9 = 0

Simplify the above expression

m² = 9

Put in the above

m = + 3 , -3

Therefore the value of the m is the equation m² - 9 = 0 are + 3 or - 3 .

The value of the m is the equation m² - 9 = 0 are + 3 or - 3 .

Step-by-step explanation:

As given the expression in the question be as follow.

m² - 9 = 0

Simplify the above expression

m² = 9

Put in the above

m = + 3 , -3

Therefore the value of the m is the equation m² - 9 = 0 are + 3 or - 3 .

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
