Answer:
121 days; 30 full days
Step-by-step explanation:
to find how much days she takes you divide 2175 by 18
2175 / 18 is 120.833333
it will take her at least 121 days because you need to round up
the last portion of the hike would be a quarter of the hike
you would divide the final time by 4 and that is your answer
121 / 4 is 30.25
you have to round down because .25 is not a full day
she hiked 30 full days
Answer:
-2x-10=4
-2x=14
x=-7
Step-by-step explanation:
Answer:
area of square= (side)^2
area = (x+1)^2 = x^2 + 2x + 1
area of rectangle = l*b = (x+10)*(2x+5) =2x^2 + 5x + 20x + 50 = 2x^2 +25x + 50
area of shaded region = area of rectangle - area of square
= 2x^2 + 25x + 50 - (x^2 + 2x + 1) = 2x^2 + 25x + 50 - x^2 -2x -1
= x^2 + 23x + 49
