The answer to number 27

Area = Length x width.

30 = w x 3w +1

Simplify:

3w^2 + w = 30

Subtract 30 from both sides:

3w^2 + w -30 =0

Factor

(w-3)(3w+10) = 0

Solve for the w's:

w = 3 and x = -3 1/3

Since the number cant be negative w = 3

The width = 3 cm.

iii.... There are 4 kings and 4 queens in each deck so (52-8)/52 which is a 44/52 chance, 0.8461 about, or 84.6% rounded

iv..., As I said in iii, there are 8 kings and queens so an 8/52 chance, about 0.1538, or 15.4% rounded
