-14+71/2= -6 1/2 degrees Celsius is the original temperature.
Answer:
90
Step-by-step explanation:
30x3=90
3rd place to the left of the decimal point is the hundreds place
so the number 4 represents 4 hundred
Let's actually find the roots, using the quadratic formula:
<span>p(x)=x^2+x+3 gives us a=1, b=1 and c=3.
-1 plus or minus sqrt(1^2-4(1)(3))
Then x = -----------------------------------------------
2
The discriminant here is negative, so the roots x will be complex:
-1 plus or minus sqrt(-11) -1 plus or minus i*sqrt(11)
x = ---------------------------------- = -------------------------------------
2 2
These are irrational roots; they cannot be expressed as the ratios of integers.</span>
