If: 9a = 18b Then: a = 2b
6a plus 18b = 24
a2
18b+9 = 9(b+2)
Difference in areas = A1 - A2 where A1 and A2 are the areas of the larger and smaller circles. Other expressions will depend on what information about the circles is available: radius, diameter, circumference.
It is "a squared minus eighteen b".
we can write it as "a2"
If: 9a = 18b Then: a = 2b
6a plus 18b = 24
a2
The GCF is 6b.
18b+9=9(b+2)
18b+9 = 9(b+2)
simplify the ratio 18b^2 to 45b
a2 + b2 = c2
18b and 24b are both divisible by 6 and they both have b so its 6b
As a to the power of 2 is the same as a squared then how about this a2
