The combined area of two squares is 45 square centimeter each side of one square is twice as long as the side of another square what is the length of each side of the larger square?

Let be the side length of the small square. Then, the side length of the big square is .

The respective areas are and

So, the sum of the areas are

We have

We can't have negative lengts, so we choose

So, the side length of the larger square is 6.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

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
