Answer:

The answer to your question is: x - 4 is not a factor

Step-by-step explanation:

x - 4 is a factor of    4x³ - 20x² + 18x -12

We can do synthetic division to know if it is a factor

                           4     - 20     +18      -12         4

                                     16      -16        8                                              

                           4       -4         +2     -4

x -4  is not a factor because there was a residue of -4

Someone please tell me what to do

For this, we need to find the area of the larger rectangle (The room) and subtract from that the area of the smaller, shaded rectangle (The rug).
A=LW (L=Length, W=Width, A=Area)

The larger rectangle first:
A=(15)(10)
A=150 feet squared

Now the Rug:
A=(12)(7)
A=84 feet squared

Now to find the area that is NOT covered by the rug, we subtract:
150-84
= 66 feet squared will NOT be covered by the rug.

Hope this Helps!

State the value of the discriminant of -6x^2 +2x + 3 = 0
Dmitry [639]

Answer:

76

Step-by-step explanation:

recall that for a quadratic equation in the form

ax² + bx + c = 0, the discriminant is given by

discriminant, D = b²- 4ac

we are given the following:

-6x² + 2x + 3 = 0,

comparing this with the general equation above, it is clear that,

a = -6, b = 2 and c = 3,

substituting these into our equation for discriminant:

D = b²- 4ac

= 2² - 4(-6)(3)

= 4 + 72

= 76
