Step-by-step explanation:
3(2x+2)=3x-15
mutiply the bracket by 3
(3)(2x)(3)(2)= 6x+6
6x+6= 3x-15
move 3x to the other side
sign changes from +3x to -3x
6x-3x+6= 3x-3x-15
6x-3x+6= -15
3x+6= -15
move +6 to the other side
sign changes from +6 to -6
3x+6-6= -15-6
3x= -21
divide by 3 for both sides
3x/3= -21/3
x= -7
Answer: x= -7

A mathematical proof may be written using a paragraph, two-columns, or using a flow chart. The two-column proof is the method we use to present a logical argument using a table with two columns. Important information is usually given to help begin a proof and is usually the starting point of all proofs.
You do C = πd which it would be 69.08
