The hypotenuse must always be c
Y=x+5
Let's say we are given that x is equal to 5.
Thus, since x=5, we can <em>replace</em> x with the number 5.
So instead of y=x+5, we now have:
y=5+5=
Another example:
x=4+y
where y= 2
x=4+2
Answer:
Ο 7 x + 4 and 3 x + 5 + 4 x - 1 When x = 2, both expressions have a value of 18.
Ο The expressions are only equivalent when evaluated with even values.
