X^2-3x-7x+16=0
x^2-10x+16=0
(x-8)(x-2)=0
x=8 or x=2
Answer: here is an example in the screenshot
it is A,B,C, or D
Step-by-step explanation:
For a given perimeter, the area will be maximized when all the sides are the same length, which makes it actually a square. A square is still a rectangle, though! So, if you know the perimeter, divide it by four to determine the length of each side. Then multiply the length times the width to get the area.
BTW U CAN USE A CALCULATOR
Answer:
37.86 mph and 40.86 mph
Step-by-step explanation:
The speed for the first session is x, for the second session will be x+3
Average speed= (x+x+3)/2= x+1.5
Total distance covered will be 228+205=433 miles
Time= 11 hours
Time= Distance/ speed
Speed= distance/time
Average Speed= 433/11
x+1.5=433/11
x+1.5=39.36363636
x=39.36363636
-1.5= 37.86363636
Approximately, x= 37.86 mph
x+3=37.86+3= 40.86 mph
