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
Answer:
1/6
Step-by-step explanation:
(3 1/3)/20=(10/3)×(1/20)=10/60=1/6
(12+8)\ 5 + 15=19... this solution works because 12+8=20.. 20/5=4 and then 4+15=19
The answer is 40 is 80% of 50 ☺
