Illusion [34]

Perimeter (P) = 2L + x

            4900 = 2L + x   ⇒  4900 - x = 2L  ⇒ \frac{4900 - x}{2} = L

Area (A) = L · x

A  = (\frac{4900 - x}{2}) (x)

Which of the following is the discriminant of the polynomial below x^2+4x+5
steposvetlana [31]

Answer:

\huge\boxed{\sf Discriminant = -4}

Step-by-step explanation:

Comparing it with quadratic equation ax^2 + bx + c = 0, we get:

a = 1 . b = 4 and c = 5

So,

Discriminant = b^2-4ac

D = (4)²-4(1)(5)

D = 16 - 20

D = -4

Hence,

Discriminant = -4

\rule[225]{225}{2}

Hope this helped!

Answer:

Carl and Alex are wearing hats.

Step-by-step explanation:

If Bob doesn't isn't wearing a hat, then Carl is, so Carl clearly is wearing a hat.

Now let's look at Alex. If he wasn't wearing a hat, then Bob would be wearing one. (If Alex doesn't wear a hat, then Bob wears

a hat). The logical conclusion is that Alex must be wearing a hat as well.
