A = 1/2bh
40 = 1/2 x^2
x^2 = 80
x = 8.9
Answer:
The value of t(x) depends on the value of x, since t is a function of x.
Step-by-step explanation:
In any function of the form "t(x)=...," the term "t(x)" represents the output value, while x represents the input value. So, the notation "t(x)=...," indicates that the value of t(x) depends on the value of x, since t is a function of x.
