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>
Answer:
no one can answer this question since it doesn't show the choices, but if whichever one is 90 degrees/ has a little square in the corner would be the right answer
Answer:
OPTION B
Step-by-step explanation:
1. You have the following formula for calculate the perimeter of a rectangle:
Where l is the lenght and w i the width.
2. Therefore, if the rectangle has the following dimensions:
You can substitute these values into the formula shown above to calculate the perimeter of a rectangle. Therefore, you obtain the following result:
