Ответ:
the integers are -28 and -29
Step-by-step explanation:
Lets do math:
When i was little this was hard but now its pretty easy
look two consecutive numbers are like 1, 2, 3, their difference is usually 1
our equation looks like this:
-57=x+(x-1)
we add 1 to both sides and get:
-56=2x
divide by 2 because im smart
-28=x
thats one number but how 'bout the other one?
we just have to subtract 1 and get -29
the end.
Ответ:
-7 +/- the square root of 49 +32 / 4
When you solve that you get x = 0.5 and x = -4
