X^2-3x-10. You solve it by foiling. I attached a photo explaining how to do it.
Speed=distance/time
distance=176km
time=2hr
speed=176km/2hr=88km/1hr
88kmph
C., because 60 is half of 120, and 12% is half of 24%
hope it is right
Given that the chip has a dimension of 8 mm by 8 mm which can be written as 0.8 cm by 0.8 cm, is drawn to scale and the dimensions of the plot is 4 cm by 4 cm, the scale of the drawing will be:
0.8 cm is represented by 4 cm
thus;
4 cm rep 0.8 cm
1 cm rep 0.2 cm
The answer is:
1 cm rep 0.2 cm
