Answer:
Step-by-step explanation:
Perimeter of the given triangle in the figure is the sum of all three sides.
The expressions for the 3 sides are given as, .
Therefore,
Simplify,
Collect like terms
11 1/2 aka D
add 7 and 4 which is 11, then add 1/4 and 1/4 which is 1/2
80%
75% + 20% - 15% = 80%
The probability is 80%
QF=gR
F=gR/Q
