The sides of a triangle are 13, 12 and 5. Find the perimeter. | (null)
------------------------
Let P=PERIMETER
Let F=FIRST
Let S=SECOND
Let T=THIRD
Given F=13
Given S=12
Given T=5
Given P=F+S+T
P=13+S+T // Substitute 13 for F in P=F+S+T
P=13+12+T // Substitute 12 for S in P=13+S+T
P=30 // Substitute 5 for T in P=13+12+T

A rectangle 20 meters longer than it is wide has an area of 125 square meters. What are the length and width? | (null)
------------------------
Find LENGTH
Find WIDTH
Let A=AREA
Let L=LENGTH
Let W=WIDTH
Given L=W+20
Given A=125
Given A=LW
A=LW // Area formula
125=(W+20)W // Substitute: L=W+20
W²+20W-125=0 // Simplify
W = { 5, -25 ) // Solve for W
W = 5 // Reject negative Width
L = 25 // Calculate L using L=W+20
End

3S=4S-18 Comment: Substitute 3S for F in F=4S-18
Step S=18 Comment Simplify
Solution S=18 //
F=54
Solution F=54 Substitute S=18 into F=3S
End
