Answer:
The answer to your question is: x1 = 0 , x2 = -1/3
Step-by-step explanation:
36x² + 12x = 0
Factorize like terms 12x( 3x + 1) = 0
Equalize to zero
12x = 0 3x + 1 = 0
x = 0/ 12 3x = -1
x = 0 x = -1/3
For this answer I believe it would be best if you did it on paper
Designing a solution by sketching a prototype for a solar panel
3 units + 1 unit = 4 units (the sum of 2nd and 3rd)
4 units + 4 units = 8 units (sum of all properties)
*The other 4 units comes from the first property as the first property's value is the same as the sum of the 2nd and 3rd.*
8 units = $560 000
1 unit = $560 000÷8 = $70 000 (3rd)
3 units = 3x$70 000= $210 000 (2nd)
$210 000 + $70 000=$280 000 (1st)
Ans:
1st property costs $280 000.
2nd property costs $210 000.
3rd property costs $70 000.
