Answer:
y= 7-2x
Step-by-step explanation:
The correct length would be 2√ units
Break 42 into 40 + 2. Multiply 40 x 7=280
and 2 x 7=14. Then add 280 + 14 = 294.
For this case, we have the following equation of the second degree:
If we divide between 2 on both sides of the equation, we will have:
Where:
The solutions will come from:
Substituting:
So, we have:
