Answer: 45 miles
Step-by-step explanation:
1 inch = 15 miles. Because there are 3 inches we will need to multiply by 3. 3 x 15= 45
Answer:
2
Step-by-step explanation:

Well the x intercept is the point the line touches the x-axis.
And to find it we need to graph the given equation.
7x - 2y = 14
Look at the image below ↓
By looking at the given image we can tell that the x-intercept is 2.
<em>Hope this helps :)</em>
Subtract 30, then factor the equation.
... x² = 30
... x² - 30 = 0
... (x -√30)(x +√30) = 0
By the zero product rule, the solutions are values of x that make a factor be zero.
... x - √30 = 0 . . . . the first factor is zero
... x = √30
... x + √30 = 0 . . . . the second factor is zero
... x = -√30
The solutions are . . .
... x = ±√30 . . . . . matches your 3rd choice
The answer should be the third one
