Answer:

Answer C

−5x3 + 4x2 − 5x; is a polynomial

Step-by-step explanation:

you just use distributive property to simplify, and then you know the closure property demonstrates that when you are adding, subtracting, multiplying, or dividing two polynomials, they will remain polynomials.

Which expression is equivalent to the expression below?(6c^2+3c/-4c+2)/(2c+1/4c-2)
algol [13]

Answer:

-3c

Step-by-step explanation:

The given expression is:

\frac{\frac{6c^{2}+3c}{-4c+2}}{\frac{2c+1}{4c-2}}

We need to simplify this expression. The rational expression in the denominator can be multiplied to numerator by taking its reciprocal as shown below:

\frac{\frac{6c^{2}+3c}{-4c+2}}{\frac{2c+1}{4c-2}} \\\\ =\frac{6c^{2}+3c}{-4c+2} \times \frac{4c-2}{2c+1}\\\\=\frac{3c(2c+1)}{-(4c-2)} \times \frac{4c-2}{2c+1}\\\\ =-3c

Thus, the given expression in simplified form is equal to -3c

Someone help me please
Mazyrski [523]

Answer:

x = -7

Step-by-step explanation:

The whole line is 12

the whole line is also   x + 14  and  x + 12

  so make them equal:

      x+14     +      x +12     = 12  

       2x   + 26   = 12        now subtract 26 from both sides

               2x = - 14           now divide both sides by 2

                 x = -7

X intercept: y = 0
y= -3/4x -4
0 = -3/4 x - 4
4= -3/4 x
4 • -4/3 = x
-5.3 = x
y intercept: x = 0
y = -3/4 x -4
y = -3/4 (0) -4
y = -4
the points are (-5.3, 0) and (0, -4)
