Because 2 squares equal a meter u have to do four up down one. (Front elevation)
Then just four by one square on second row down(side elevation)
Distribute the 5
25t-10=-35
+10 +10
25t =-25
divide by 25 on both sides
t=-1
Im pretty sure is teh 3rd one
Transitive property states:
If A = B and B = C, then A = C
In this case, 2 + 8 = 4 + 6 and 4 + 6 = 10. If you call A = 2+8, B = 4+6 and C = 10, using Transitive property you can conclude that 2 + 8 = 10
