Answer:
speed greater than 0.08 mi/min
Step-by-step explanation:
given data
distance = 2 mi
time = 25 min
to find out
the distance you travel and your speed and time related
solution
we know that distance is
distance = speed × time ...............1
so at park at most 25 min
so we need time = 
so here
we know

so

so we can say that he need to run at speed greater than 0.08 mi/min
Answer: THe equation C²=36 can have both -6 and 6 as possible values since -6 squared is 36 and so is 6 squared

Now completing the square.

(x+5)² = 16 is the rewritten equation... For first question btw.
For the solutions to the equation -

x = -1,-9 is the solution, for the second question.
(3x+1) = 64
3x = 63
3x/3 = 63/3
x = 21
