This is a right triangle (you can confirm by using Pythagorean Theorem: 15² + 36² = 39²)
A = 
A = 
= 15 * 18
= 270
Answer: 270 cm²
9514 1404 393
Answer:
B. dp = k
Step-by-step explanation:
The statement of variation is ...
d = k(1/p) . . . . days vary inversely with p
Multiplying by p gives ...
dp = k
This equation is written in slope-intercept form (y=mx+b), which means that the equation will give you the slope and y-intercept. The variable m is the slope, and b is the y-intercept.

8t-(5-2t) = 5(2t-1)
distribute the negative on the left side, distribute on the right
8t-5+2t = 10t-5
combine like terms
10t-5 = 10t-5
t=0 or (-infinity, infinity)
