2.find two consecutive even whole numbers whose product is 168
with solution pls

Answer 1

First question:

49 less than square of a number is zero.

Let the number be x.

x^2-49 = 0

x^2 = 49

x=7

Number is 7

Second question:

1,2,3,4,6,7,8,12,14,21,24,28,42,56,84,168 are factors of 168

2,4,6,8,10,12,14, etc. are even numbers

From above, 2,4,6,8,12,14, are even factors of 168

12*14= 168

12 and 14 are two consecutive even whole numbers whose product is 168
