How many solutions does the equation have?
borishaifa [10]
First we have to distribute the parentheses on the left side, 2*x is 2x and 2*-3 is -6, so now the equation is 4x+2x-6 = 8x+12
Then, we can add together the two x's on the left side,
so now we have 6x-6 = 8x+12       Subtract 12 from both sides and
you get 6x -18 = 8x    Then you can subtract 6x from both the sides and get
-18 = 2x  Now we can divide both sides by 2, and the final answer is -9 = x
Since they are not the same and the two sides aren't unequal, there is one solution(:
Hope this is helping you(:

the lengths of the side of a rectangular window have the ratio 1.7 to 1 the area of the window is 2,720 sqaure inches what are d
nignag [31]

Answer:

Lenght: 68\ in\\\\Width: 40\ in

Step-by-step explanation:

The formula for calculate the area of a rectangle is:

A=lw

Where "l" is the lenght and "w" is the width.

You know that the ratio  of the sides of the rectangular window is:

1.7:1

 Then, let be x the width (in inches) of the rectangular window and 1.7x the lenght (in inches) of the rectangular window.

Knowing that the area of the window is 2,720 square inches, you can know that:

(1.7x)(x)=2,720

Now you must solve for "x" in order to find the width:

(1.7x)(x)=2,720\\\\1.7x^2=\\\\x=\sqrt{\frac{2,720}{1.7} }\\\\x=40

Finally, the lenght is:

1.7x=1.7(40)=68
