Firstly, you have yo multiply out the first bracket by multiplying (2x - 5) by 4. The equation would then look like:
8x - 20 = 5x - 20 + 3x
Then you have to put normal numbers on one side and x-terms on the other. It would look like:
-20 + 20 = 5x + 3x - 8x
Then you should solve the additions and subtractions
0 = 0x
Since ANY number multiplied by 0 is zero, your equation has infinite solutions.
Area of the 3 rectangles that make up the prism:
30 * 25 + 30 * 17 + 30 * 28 = 2100
Area of the two triangles at either end:
Use bh/2
(15 * 28)/2 = 210
There are two so it’s 420
2100 + 420 = 2520cm^2
when the song is at 1, the cost is 0.99, when the songs are at 2, the cost is $1.98
Divide the cost by the number of song: 1.98 / 2 = 0.99 per song.
The unit rate is $0.99 per song.
