Answer:
Their goal was to collect 125 toys.
Step-by-step explanation:

=

Whatever you do to one side you must do to another. To get from 80 to 100% of your goal, you must multiply 80 by 1.25 . Because we did this to one side, we had to do it to the other. 100 toys multiplied by 1.25 is 125 toys.
You know that a perfect square trinomial is given by square of first term, twice the product of first and last terms and square of second term
So we have x^2 that is square of x, 2x that is twice the product of x*1, the second term shoulf be 1, that is square of 1
So your answer would be 1
If you try (x+1)^2 = x^2+2x+1
speed = distance / time = 100 m / 50 s = 2 m/sec
Juan average speed is 2 m / sec
