text: 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!  key: *= squared  36. (x-7)*=5  42. (3x-2)=11  44. (x-3)*=7  46. (x+2)*=60  48. (x-2.1)*=90  38. x*-4x+4=10  40. x*+6x+9=27  50. x+9x+10=9x+34  52. (x+6)(x-2)=4(x+9)  54. 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?  56. 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?  58. 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?  60. if the square of 3 more than a number equals 10, what is the number?  62. the area of a circle is 100 pi cm*. if the area is doubled, how much is added to the circumference? 36.  (x-7)*=5 take square root of both sides leaves you with x-7=2.2361 +7=+7 x=9.2361  42. 3x-2=11 +2=+2 3x=13 /3=/3 x=13/3 or 4 1/3  44. similar to 36 (x-3)*=7 square root both sides leaves you with x-3=2.6458 +3=+3 x=5.6458  46 & 48 are similar to 36 and 44  38. x*-4x+4=10 foil out, rewriting equation (x-2)(x-2)=10 square root both sides gives you x-2=3.1623 +2=+2 x=5.1623  40. is similar to 38 above  50.  x+9x+10=9x+34 10x+10=9x+34 -10=-10 10x=9x+24 -9x=-9x x=24  52. (x+6)(x-2)=4(x+9) x*-2x+6x-12=4x+36 x*+4x-12=4x+36 -4x=-4x x*-12=36 +12=+12 x*=48 square root x*=square root 48 x=6.9282  will try 54,56,58,60,62 if i solve any will modify my answer. hope this helps.  54. (s+5)*=80 square root both side leaves you  s+5=8.9443 -5=-5 s=3.9443  56.  200=14.142135* trying to get to 100=10* less reduce by 4.1421  58.  is sqaure root of 14 = 3.7417m  60.  (3+x)*=10 square root both sides leaves you with 3+x=3.1623 -3=-3 x=.1623  62.  sorry not very good with circles.  hope i helped you lots.  good luck.
