Question: HOW do you solve these kinds of problems? HELP!: HOW do you solve these kinds of problems? Also, what are their outcomes? Thank you very much! I don't understand these AT ALL whatsoever!\n\nKEY: *= squared\n\n36. (x-7)*=5\n\n42. (3x-2)=11\n\n44. (x-3)*=7\n\n46. (x+2)*=60\n\n48. (x-2.1)*=90\n\n38. x*-4x+4=10\n\n40. x*+6x+9=27\n\n50. x+9x+10=9x+34\n\n52. (x+6)(x-2)=4(x+9)\n\n54. Each side of a square is increased by 5 cm in order to make a square with an area of 80 cm*. What is the length of each side of the original square?\n\n56. A square has an area of 200 m*. By how much should each of its sides be decreased in order to form a square with half the area of the original square?\n\n58. A square room has a ceiling area of 14 m*. How many meters of trim are needed to cover the edges where the ceiling joins the wall?\n\n60. If the square of 3 more than a number equals 10, what is the number?\n\n62. The area of a circle is 100 pi cm*. If the area is doubled, how much is added to the circumference?

Answer: 36.  (x-7)*=5\ntake square root of both sides leaves you with\nx-7=2.2361\n+7=+7\nx=9.2361\n\n42. 3x-2=11\n+2=+2\n3x=13\n/3=/3\nx=13/3 or 4 1/3\n\n44. similar to 36\n(x-3)*=7\nsquare root both sides leaves you with\nx-3=2.6458\n+3=+3\nx=5.6458\n\n46 & 48 are similar to 36 and 44\n\n38. x*-4x+4=10\nFOIL out, rewriting equation (x-2)(x-2)=10\nsquare root both sides gives you x-2=3.1623\n+2=+2\nx=5.1623\n\n40. Is similar to 38 above\n\n50.  x+9x+10=9x+34\n10x+10=9x+34\n-10=-10\n10x=9x+24\n-9x=-9x\nx=24\n\n52. (x+6)(x-2)=4(x+9)\nx*-2x+6x-12=4x+36\nx*+4x-12=4x+36\n-4x=-4x\nx*-12=36\n+12=+12\nx*=48\nsquare root x*=square root 48\nx=6.9282\n\nWill try 54,56,58,60,62 if I solve any will modify my answer. Hope this helps.\n\n54. (s+5)*=80\nsquare root both side leaves you \ns+5=8.9443\n-5=-5\ns=3.9443\n\n56.  200=14.142135*\ntrying to get to 100=10*\nless reduce by 4.1421\n\n58.  Is sqaure root of 14 = 3.7417m\n\n60.  (3+x)*=10\nsquare root both sides leaves you with\n3+x=3.1623\n-3=-3\nx=.1623\n\n62.  Sorry not very good with circles.  Hope I helped you lots.  Good luck.
