Answer:
A = 24t² + 2t
Step-by-step explanation:
The shaded area (A) is calculated as
A = area of outer square - area of rectangle
= (5t)² - t(t - 2)
= 25t² - t² + 2t
= 24t² + 2t
21/10+5/10
Add nominators since denominators are the same.
26/10
Or 2 6/10 as a mixed number.
For this case we have the following linear function:

What we must do is equal the function to zero or equivalently, substitute the value of y = 0 in the given function.
We have then:

From here, we clear the value of x.
We have then:
Answer:
all real zeros of the function y = 2x-4 are:
x = 2
the denominator would be 12
7000 + 224.16 = $7,224.16
This would the balance in her account.
