The anser for 6 is 25/92
The answer for 7 is 1 1/2
Answer:
If the roots of an equation are x = -1 ± i, it means that the factorized form of that equation is: (x + 1 + i)(x+ 1 - i) = 0.
Using the distributive property, we have:
(x + 1 + i)(x+ 1 - i) = x^2 + x - ix + x + 1 - i + ix + i + 1
Combining like-terms and simplifying:
⇒ x^2 + x + x + 1 + 1 = x^2 + 2x + 2 = 0
Therefore, the stament is correct. If the roots of an equation are x = -1 ± i, then the equation is: x^2 + 2x + 2 = 0.
Answer:
3 1/2 gallons of paint
Step-by-step explanation:
1 5/8 - 5/6 = x
Turn the mixed number into an improper fraction:
1 5/8 = 13/8 = x
13/8 - 5/6 = x
make the denominator the same:
13/8 * 3 = 104/24
5/6 * 4 = 20/24
Subtract:
104/24 - 20/24 = 84/24
Simplify:
84/24 divided by 6 = 14/4
14/4 divided by 2 = 7/2
Turn into a mixed number:
3 1/2
