Answer:

\boxed{ \frac{cd}{e} = - 15}

Given:

c =  - 9 \\ d =  - 20 \\ e =  - 12

Step-by-step explanation:

=  >  \frac{cd}{e}  \\  \\  =  >  \frac{( - 9)( - 20)}{( - 12)}  \\  \\  =  >  \frac{9 \times 20}{( - 12)}  \\  \\  =  >  -  \frac{180}{12}  \\  \\  =  >  - 15

Solve for x: 6 x2 + 2x - 3 2 = 0
Zigmanuir [339]

I think the answer is 10 because:

6x2=12

12+2x-32=0

make the like terms together = 12-32+2x=0

= -20+2x=0

again make the like terms together = 2x=0+20 [sign changes when it goes to the other side]

so, 2x=20

x=20/2 [ multiplication will change into division when it goes to the other side]

therefore x=10

A police officer seals off the scene of an accident using a roll of yellow tape that is 272 feet long. What dimensions should be
klasskru [66]

Answer:

  68 feet square

Step-by-step explanation:

The rectangle with the maximum area for a given perimeter is a square. The perimeter of a square is 4 times the side length, so the side length of the square area will be ...

  (272 ft)/4 = 68 ft

_____

<em>More formally ...</em>

You can let x represent the length of one side. Then the length of the other side for the given perimeter will be 136 -x, and the area will be the product ...

  area = x(136 -x)

The area function is a quadratic with zeros at x=0 and x=136. The vertex (maximum area) will be at the value of x that is on the line of symmetry between these points, at their midpoint: x = (0 +136)/2 = 68. This value of x makes the rectangle a square.
