Answer:
x = 0, 9/2
Step-by-step explanation:
6x^2 - 27x = 0 (original)
3x(2x - 9) = 0 (factor out GCF of 3x)
|
v
(solve each factor (3x and 2x - 9) for x)
3x = 0
x = 0
2x - 9 = 0
2x = 9
x = 9/2
Answer:
139
Step-by-step explanation:
if one side is 139 the other side is 139
42/12 = 3.5, 63/18 = 3.5, therefore we will be multiplying the last time by 3.5. 40x3.5= 140, and therefore, the number of pencils produced in 40 seconds is 140
