X^2 - 14x + 49 

2 numbers that multiplied equal 49
2 number that added equal -14

-7 times -7 = 49
-7 plus -7 = -14

(x-7) (x-7)

x=7

The value of the solid's surface area is equal to the value of the solid's volume. Find the value of x.
USPshnik [31]
Volume = (l * w * h) or (11 * 3 * x)  which will equal surface area.  Volume is 33x for now

Surface Area = 2 (x * 11) + 2 (x * 3) + 2 (11 * 3)

Set Volume equal to surface area. I simplified SA already.
33x = 22x + 6x + 66

33x - 28x = 66

5x = 66

x = 66/5 or 13.2

1/3(33x +15) - 1/3 ( 21x +18) =10
inn [45]
          ¹/₃(33x + 15) - ¹/₃(21x + 18) = 10
¹/₃(33x) + ¹/₃(15) - ¹/₃(21x) - ¹/₃(18) = 10
                             11x + 5 - 7x - 6 = 10
                             11x - 7x + 5 - 6 = 10
                                            4x - 1 = 10
                                                + 1   + 1
                                                 4x = 11
                                                  4      4
                                                   x = 3³/₄
