Determine the number of solutions that exist to the equation. 8(j-4)=2(4j-16)

lukranit [14]

<span>8(j-4)=2(4j-16)
8j - 32 = 8j - 32

Since both sides are equal, there are is an infinite number of solutions.

How much will you pay for a used Samsung S20 which is sold for $170 with a discount of 20% if you are a "Remote Only" student?

136$

you find 20% of 170 by multiplying 0.2*170=34 then you’d subtract 170-34 to get 136

= (-4-4)/(7-3)

= -8/4

= -2

Given:

Length of a rectangle = (3x-3)

Width of the rectangle = (2x+1)

To find:

The area of the rectangle.

Solution:

We know that, area of a rectangle is

$Area=Length \times width$

Putting Length = (3x-3) and width = (2x+1), we get

$Area=(3x-3)\times (2x+1)$

$Area=(3x-3)(2x+1)$

Using distributive property, we get

$Area=3x(2x+1)-3(2x+1)$

$Area=3x(2x)+3x(1)-3(2x)-3(1)$

$Area=6x^2+3x-6x-3$

$Area=6x^2-3x-3$

Therefore, the area of rectangle is $(3x-3)(2x+1)\equiv 6x^2-3x-3$ sq. units.
