yes on the first.
On the second, add the lengths. What is 5/4 + 2/4 + 4/4 ?
1. you toss three coins. what is the probability P that all are heads?
2. write and simplify an expression for the perimeter of a triangle with these lengths: 1/2x, x, 5/4x
for number one, i think it might be 1/8

2 3/4
so is this (5/4 + 2/4 + 4/4) the expression?
so is this (5/4 + 2/4 + 4/4) the expression?
The expression is...
Perimeter=5/4 x + 1/2 x + x
simplifying, you get
Perimeter= 2 3/4 x
Perimeter=5/4 x + 1/2 x + x
simplifying, you get
Perimeter= 2 3/4 x
