The correct answer is x=3.5
Volgvan3 years ago
5 0

Answer: x = 3.5

Step-by-step explanation:

We can start by subtracting 5 from both sides:

2x - 5 = 12 - 5      Which will come out to: 2x = 7

Then we divide both sides by 2 so that we can isolate the variable:

2x/2 = 7/2       Which will come out to: x = 3.5

Quadrilateral ABCD has vertices AC-3.6), B(6,0), C(9. -9), and D(0, -3). Prove that ABCD is a) a parallelogram​
Nata [24]

9514 1404 393

Explanation:

The quadrilateral will be a parallelogram if the diagonals bisect each other. That will be the case if the sums of their end-point coordinates are the same.

  A + C = (-3, 6) +(9, -9) = (6, -3)

  B + D = (6, 0) +(0, -3) = (6, -3)

Both diagonals have their midpoint at (3, -1.5), so the diagonals are mutual bisectors. The figure ABCD must be a parallelogram.

___

The midpoint of AC is (A+C)/2 = (6, -3)/2 = (3, -1.5).

two boxes of identical birthday candles are pictured: a 2 ounces box and 6- ounces box. There is 96 candles in the large box. Ho
Sladkaya [172]

Answer:  There are 32 candles in the small box.

Step-by-step explanation:

Since we have given that

Size of small box= 2 ounces

Size of large box = 6 ounces

Number of candles in large box = 96,

We need to find the number of candles in the small box ,

As there is direct variation between the small box and large box ,

let the number of candles in the small box be x

So,

\frac{96}{6}=\frac{x}{2}\\\\16=\frac{x}{2}\\\\16\times 2=x\\\\32=x

so, there are 32 candles in the small box.

If a rectangle has an area of x^2+x-20 and a width of x-4, what is the length?
Mrac [35]

Answer:

This (x - 5) represents the length of the rectangle.

Step-by-step explanation:

The formula for the area of a rectangle of length L and width W is A = L * W.

Here, the width is x - 4 and the area is x^2 + x - 20.  Dividing the width (x - 4) into the area results in an expression for the length:

x - 4  /   x^2 + x - 20

Let's use synthetic division here.  It's a little faster than long division.

If the divisor in long division is x - 4, we know immediately that the divisor in synthetic division is 4:

4   /   1    1    -20

              4     20

    --------------------

         1     5     0

This synthetic division results in a remainder of 0.  This tells us that 4 (or the corresponding (x - 4) is indeed a root of the polynomial x^2 + x - 20, and so *(x - 4) is a factor.  From the coefficients 1 and 5 we can construct the other factor:  (x - 5).  This (x - 5) represents the length of the rectangle.
