Newborn = 18 inches
adult boa = 9 * 18 + 2 = 164 inches
Since all the information is given, then merely put the necessary facts in order.
Had the length of the newborn been unknown, it would have been represented by x.
9x + 2 = 164
9x = 164 - 2
9x = 162
9x/9 = 162/9
x = 18
Answer:
length = 8
width = 4
Step-by-step explanation:
Area = length x breadth
Let x represent the width
length = x + 4
32 = x × (x + 4)
32 = x² + 4x
x² + 4x - 32 = 0
solving using quadratic equation =
(x² - 4x) -32 + 8x
x = 4 or -8
since width cannot be a negative number, we would use 4
