Answer:
<em>16 -> 15/20 -> 0.65 -> -7/25</em>
Step-by-step explanation:
<u>Why?</u>
Most of the numbers in the set are rational where there is only ONE nature number which is 16 and it's the greatest. Comes after is 15/20 which equals .75 and it's obviously larger than 0.65 which will come after. The negative number is the smallest so it goes last :)
Answer:
25
Step-by-step explanation:
because you have to divide by 15's
Answer:
n = -5, 3.
Step-by-step explanation:
n^2 + 2n - 15 = 0
Let's check if we can factor this quadratic:
We need 2 numbers whose product is -15 and whose sum is +2.
There are 2 such numbers and they are +5 and -3, so the factors are:
(n + 5)(n - 3) = 0.
n + 5 = 0 or n - 3 = 0
therefore the zeroes are -5 and 3.
Answer:
Step-by-step explanation:
There are several approach to solving a quadratic equation; factorization, completing the square, the use of 'the almighty formula etc. Though i didn't see the steps you followed in solving, but from your answer, it is obvious you made good attempt but something is missing, your answer should be (5+√57)/2 or (5-√57)/2
the values of x are -7/5 and -7/8 .
