Answer:
69 miles
Step-by-step explanation:
Put the number in place of the variable representing it and do the arithmetic.
L = 41 +28 = 69
After 28 days, the length of the road is 69 miles.
The question is asking to calculate the zeros of the function f(x)=(5x^2+2x)/x, base on that and in my further calculation, the possible answer would be x=5. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications
<h3>
You need to add 4 to both sides</h3>
The x term has a coefficient of 4. Take half of this to get 2, then square it to get 4. This is the value we add to both sides to get x^2+4x+4 = 5. Note how x^2+4x+4 factors into (x+2)^2
---------
Another example: Let's say we started with x^2+6x = 1. To complete the square, we need to add 9 to both sides. I start with 6 (the x coefficient) and cut that in half to get 3, then I squared that to get 9. So we add 9 to both sides getting x^2+6x+9 = 10 which becomes (x+3)^2 = 10
Answer:
137.12
Step-by-step explanation:
Density = mass/volume
Density = 3.51
Mass = 481.3
Thus: 481.3/3.51 = 137.122507123
