The diagram shows a square with perimeter 20cm. Work out the percentage of the area inside the square that is shaded.

Idon’t understand! use slope intercept form to solve: through: (2,5) slope= undefined

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?

When 142 is added to a number the result is 64 more then 3 times the number. option 35 37 39 41
