D'un solar es van vendre 2/3 parts de tota la superificie i despres 2/3 parts del que quedava. L'ajuntament va expropiar els 3200m2 restants per fer un parc públic. Quina era la superficie solar?

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

c and d is your answers.

stay frosty!
