part 2
I can't so please help me
2( n+7)-7=9
multiply the bracket by 2
(2)(n)=2n
(2)(7)=14
2n+14-7=9
2n+7=9
move +7 to the other side
sign changes from +7 to -7
2n+7-7=9-7
2n=9-7
2n=2
divide both sides by 2 to get n by itself
2n/2=2/2

Answer:
31.4
Step-by-step explanation:
Each side of the square has a length of 40 × = 10 inches. 4
The perimeter of the square minus the circumference of the circle is 40 − 31.4 = 8.6
The radius of the circle is 10 = 5 inches, so the circumference of the circle is 2
2 × π × 5 = 10 × 3.14 = 31.4 inches.
