how do you find the scale factor of two circles
The dilation of 22 with scale factor 2.5 is 55.The formula for finding a dilation with a scale factor is x' = kx (k = scale factor), so x' = 2.5(22) = 55.
A scale factor is the ratio of corresponding linear measures of two objects.A scale factor is the ratio of corresponding linear measures of two objects.A scale factor is the ratio of corresponding linear measures of two objects.A scale factor is the ratio of corresponding linear measures of two objects.
There are lots of different types of problems in algebra; you have to learn each type separately. For example, how to add similar expressions; how to multiply expressions; how to factor polynomials; how to solve equations; etc.
The two scale factors are reciprocals of one another.
That depends on what the problem is.
Scale drawing.
21 and 84

4 is not a factor of 998
I factor because the problem I'm solving calls for it. It's the fastest and easiest way to solve for the GCF or LCM.
Multiplying each factor by powers of ten
It might help, but it's not likely to be a large scale contribution to the solution of the problem.
You increase the scale factor.
Tautologically!
The area scale factor is the square of the side length scale factor.
It is to use science for a practical job or to solve a problem.
