What is the smallest whole number larger than the perimeter of any triangle with a side of length 55 and a side of length 1919
erastova [34]

Answer:

If the third side is x, then

The perimeter is 5+19+x.

But every side must be less than the sum of the other

    two sides, so x < 5+19

                  x < 24

Adding 5+19 to both sides to make the left side

equal to the perimeter

 perimeter = x+5+19 < 24+5+19 = 48

So 48 is the smallest whole number that is larger than the

perimeter of any triangle with a side length of 5 and a side

length of 19.

Find all the zeros of f(x).
Vitek1552 [10]

Answer:

The zeroes are -6, 1/2 and 2.

Step-by-step explanation:

f(x) = 2x3 + 7x2 - 28x + 12 = 0

From the first and last coefficient 2 and 12, one guess for a zero is x = 2.

So substituting x = 2:

f(2) = 16+ 28 - 56 + 12 = 0

So x = 2 is a zero and x - 2 is a factor of f(x)

Performing long division:

x - 2)2x3 + 7x2 - 28x + 12( 2x2 + 11x - 6 <------- Quotient

       2x3  - 4x2

                 11x2 - 28x

                 11x2 - 22x

                          - 6x + 12

                           -6x + 12

                            .............

Now we solve

2x2 + 11x - 6 = 0

(2x - 1)(x + 6) = 0

2x - 1 = 0 or x + 6 = 0, so:

x = 1/2,  x = -6.
