Answer:
14
Step-by-step explanation:
56 divided by 7 = 8
14 divided by 7 = 2
hinting at 8/2
56 57 and 58 are the three numbers that work
for an isosceles right triangle the legs would be 2 times the square root of the hypotenuse
so for this:
the legs would be 2sqrt(10)
The answer would be 3z(5x + 7y)
That makes no sense at all!!!
