Answer:

x = -4

Step-by-step explanation:

Recall the Order of Operations rules:

Any work enclosed in parentheses must be done first if possible; in this particular problem, nothing inside parentheses is possible.

Next: multiplication and division, and

Finally: addition and subtraction.

Thus, we must focus on the multiplication -3(4x - 8) and 3(-8x - 1) first:

-3 -16x + 32 = -24x - 3

Adding 3 to both sides simplifies this equation to -16x + 32 = -24x.

Adding 16x to both sides isolates x on the right side: 32 = -8x.

Finally, x = -32/8, or x = -4

Step-by-step explanation:

-3-4 -32x=3×8x

-3-4-32x=24x

-6=32x+24x

-6=56x

:. x=-28/3

Okay. So first you subtract 2x from each side. That will give you 4y= -2x+18 (you want to get y by itself). Then you divide both sides by 4. It should equal> y= 1/2x +9/2

The combined area of a pair of congruent rectangles can be represented, in square units, by the expression 18y^2-818y 2 −8. The

Answer:

$Perimeter = 12y$

Step-by-step explanation:

Given

$Area = 18y^2 - 8$ -- two rectangles

Required

Determine the perimeter of one of the rectangles

First, calculate the area (A) of 1 rectangle

$A =\frac{1}{2}Area$

$A =\frac{1}{2}(18y^2 - 8)$

$A =9y^2 - 4$

Express as difference of two squares

$A =(3y - 2)(3y+2)$

Area is calculated as:

$A = Length * Width$

So, by comparison:

$Length = 3y - 2$

$Width = 3y + 2$

The perimeter is:

$Perimeter = 2 *(Length + Width)$

$Perimeter = 2 *(3y-2+3y+2)$

Collect Like Terms

$Perimeter = 2 *(3y+3y-2+2)$

$Perimeter = 2 *(6y)$

$Perimeter = 12y$
