"Eight is" means 8 equals"5 less than" means minus 5"twice the number r" means r times 2
Therefore, the equation is 8 = 2r - 5
Solve:
8 = 2r - 5
Add 5 on both sides:
8 = 2r - 5
+5 +5
13 = 2r
Divide by 2 on both sides:
13 = 2r
/2 /2
6.5 = r

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
