Answer:
2 numbers could be 10 and 12
or - 12 and - 10
Step-by-step explanation:
let the 2 numbers be x and x + 2
since they are 2 consecutive even numbers, the difference between them is 2
the difference between the reciprocals is 1/60
we have to mulitply the 2 denominators x and (x+2) to get a common denominator for the 2 fractions
=
we can then remove the brackets from the numerator and denominator
and then cross multiply
60 * 2 = x² + 2x
120 = x² + 2x
x² + 2x - 120 = 0
we have a quadratic equation which needs to be solved
x² + 12x - 10x - 120 = 0
x (x + 12) - 10(x + 12) = 0
(x - 10) (x + 12) = 0
x - 10 = 0 or x + 12 = 0
x = 10 x = -12
Answer:
i don't know this i think its 3.4 or 1.9
Answer:
A
Step-by-step explanation:
Given
- 2x(5x - 2) = 0
Equate each factor to zero and solve for x
- 2x = 0 ⇒ x = 0
5x - 2 = 0 ⇒ 5x = 2 ⇒ x = 
Solutions are
x = 0, x =
