Yeah not just one letter but two letters perpendicular to another two letters. Each 2 letters like AB is a straight line which is crossed by another 2 letters making it perpendicular.
The expression is 5x - 2y
Use PEMDAS and work out the rest
x = 3 and y = 4
5 x = 5 x 3 = 15
2 y = 2 x 4 = 8
15( x ) - 8 (y) = 7
The answer is 7
Hope This Helps You!
Good Luck Studying :)

Answer:
A)
f(t) = 50 * 1.2^t
B)
f(3) = 50 * 1.2^3 = 86.4 tree frogs
C)
f(t) = 50 * 1.2^t = 200 --> t = LN(200/50)/LN(1.2) = 7.604 years
D)
f(-1) = 50 * 1.2^(-1) = 41.67 tree frogs
