The area of the square is 81 sq in, and the area of the circule is (3.14)(3 in)^2, or approx 3.14(9) sq in, or approx 28.27 sq in.
Subtract: 81 sq in - 28.27 sq in = approx. 52.73 sq in.
The difference is 52.73 sq in; the square is larger, the circle smaller.
The answer would be -2
(4-10)-(8 ÷(-2))
(-6)-(-4)
-6+4
-2
The answer is:
an=4000n+38,000
Sam has $42,000 one year after graduating. So when he graduates, he would have $38000.
Hope this helps!
