7623, 27.8, 76.9, and 8401 it is really simple just use a calculator........
Answer:
36900
Step-by-step explanation:
It's a linear function with equation P(t)=900+600*t. P(60)=900+600*60=36900
It is

The equation for area of a trapezoid is

Substituting our values in

We can then simplify the expression

Given:
• AD = 3
,
• DC = 27
,
• BD = x + 3
Let's solve for x.
To solve for x, apply the altitude formula:

Where BD is the altitude.
Cross multiply:

Plug in the values and solve for x:

Take the square root of both sides:

Therefore, the value of x is 6 .
