6/42 in simplest form :
Divide both the nominator and the denominator by the HCF (highest common factor) : 6
6/42 = 6:6/42:6 = 1/7
Answer:
11y + 2x + 12
Step-by-step explanation:
put similar numbers together:
1. 7y + 4y = 11y
2. 8 + 4 = 12
3. 2x has no match so it is left alone
Put the numbers back together into a new equation: 11y + 2x + 12
Answer:
255.8
Step-by-step explanation:
first
1/6*1535
=255.8
(x²+9)*(25(x²-4x+4))
x=±√-36/2, so x=±3i
x=4±√(16-16)/2, so x=2 is a double root
depends on how your teacher instructed you to county roots. there are 2 complex solutions and two real solutions because 2 is a double root. that would be D. however there are only 3 DISTINCT roots, , 3i, -3i, and 2 which would be C. The CORRECT answer to a mathematician would be D
The first step would be to cross multiply:
x 4
-- = ---
2 12
12x = 8.
Solve the equation from there. :)
