The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.
The distributive property can be represented as:
a(b + c) = ab + bc
Let us consider a expression
30 + 5x
We have to write a equivalent expression
Use the distributive property
30 = 6 x 5
Thus 30 + 5x becomes,
Factor out 5 from above expression
Thus, equivalent expression is 5(6 + x) for 30 + 5x

The standard form of an equation of a circle:
(h, k) - center
r - radius
We have the center (0, 3) and the point (-1.5, 3) on the circumference.
The radius is a distance between given points: r = 1.5.
