Mai has a rectangular poster. The poster is 1.6 meters long and 1.2 meters wide.
dangina [55]

Answer:

19,200 cm^2.

Step-by-step explanation:

The area = 1.2 * 1.6 = 1.92 m^2.

There are 100 cm to 1 meter,  so 1 square meter = 100^2 = 10,000 cm^2.

Therefore 1.92 m^2 = 10,000 * 1.92 =  19,200 cm^2.

Solve the equation 5x-2x^2+1
Pani-rosa [81]

Answer:

Step-by-step explanation:

If you call "5x-2x^2+1" an "equation," then you must equate 5x-2x^2+1 to 0:

5x-2x^2+1 = 0

This is a quadratic equation.  Rearranging the terms in descending order by powers of x, we get:

-2x^2 + 5x + 1 = 0.  Here the coefficients are a = -2, b = 5 and c = 1.

Use the quadratic formula to solve for x:

First find the discriminant, b^2 - 4ac:  25 - 4(-2)(1) = 25 + 8 = 33

Because the discriminant is positive, the roots of this quadratic are real and unequal.

                                                             -b ± √(discriminant)

Applying the quadratic formula   x = --------------------------------

                                                                         2a

we get:

      -5 ± √33           -5 + √33

x = ----------------- = --------------------- and

           2(-2)                     -4

                                  -5 - √33

                                 ---------------

                                         -4
