Answer
second one
Step-by-step explanation:
The answer is 18, the answer is always just the number in the brackets( hope this helps)
Since x represents the length (in meters), the width, which is 7 meters greater, is x +7. The product of these dimensions is the area (in square meters):
x(x +7) = 170
In standard form, the quadratic is ...
x² +7x -170 = 0
Equation 2 is the only linear one due to the fact that there is no exponent on the x or y values.
0.647 rounded to the nearest tenth = 0.6
