Answer: 48.84
Step-by-step explanation:
First, find the perimeter of the rectangle. 12+12+3+3=30ft. Next, find the perimeter of the semicircles. You can tell that if you put the semicircles together it would be a full circle. The formula for the perimeter of a circle is r2pi. The radius times 2 would be 6. Pi is approximately 3.14. 6 times 3.14 is 18.84. 18.84+30=48.84ft. Hope this helped :)
Well...
ABC = 53 degrees
Because;
Add 40 and 13.
So 8x^2+8x+8-(-9x^2+2x+5) is going to be
8x^2+9x^2+8x-2x+8-5
Giving you
17x^2+6x+3
