If you mean: x squared -7x +12 then it is (x-3)(x-4) when factored .
The total area of the rectangle would be 768.
The area of the the circle ( 2 semi circles added ) would be 452.16.
If you subtract these two areas you get your answer.
768-452.16=315.84
*The way pi is used can change the value of the decimal.*
I don’t really know? What grade is this?
You need 12 square roots of 1764 ?
Why not find the square root of 1764 first (it's 42) and then take 12 of those ?
Answer:
The correct answers are
Sal walks 14 km in 4 h
Sal walks 3.5 km in 1 h
Step-by-step explanation:
Given:
Distance represented by Y axis in kilometer.
Time represented by X axis in hour,
The graph of line is showing distance walked. And the two points are (1, 3.5) and (4, 14).
In plotting of points the first coordinate is always the X coordinate that is time in hour here, and the second coordinate is always the Y coordinate that is distance in km.
Therefore, the given below two options are correct
Sal walks 14 km in 4 h
Sal walks 3.5 km in 1 h
