12 x 2 = 42 14 x 3 = 42 7 x 6 = 42 6 x 7 = 42 2 x 12 = 42 3 x 14 = 42
No, 6 x 7 = 42, and 7 x 7 = 49.no
7x = 42 so x = 42/7 and therefore x = 6
42 x 7 = 294
42 square feet
The prime factorization of 42 is 2 x 3 x 7.2 x 3 x 7 = 422 x 3 x 7 = 42
-x2 + x + 42 = -[x2 - x - 42] = -[x2 - 7x + 6x - 42] = -[x*(x - 7) + 6*(x - 7)] = -(x - 7)*(x + 6)
12 x 2 = 42 14 x 3 = 42 7 x 6 = 42 6 x 7 = 42 2 x 12 = 42 3 x 14 = 42
No, 6 x 7 = 42, and 7 x 7 = 49.no
42 = 1 x 42, 2 x 21, 3 x 14, 6 x 7, 7 x 6, 14 x 3, 21 x 2, 42 x 1
7x = 42 so x = 42/7 and therefore x = 6
6
-x2 + x + 42= -x2 + 7x - 6x + 42= 7x - x2 + 42 - 6x= x(7 - x) + 6(7 - x)= (7 - x)(x + 6)
42 x 7 = 294
As a product of its prime factors: 2*3*7 = 42
2 x 3 x 7 = 42
