The pieces are 2.5 and 7.5 the 7.5 is the piece that is 3 times the length of the first one
Answer: The first.
Step-by-step explanation: If you draw out a triangle and lable the points on each point with values from each triangle, you get J=M, K=N, and L=O. The first is the only one that proves it.
So to factor
factor out a x+z
(x+z)(x^2-xz+z^2)
the factors are
x+z and x^2-xz+z^2
They are the same because 14 is 2*7 and 21 is 3*7.
Answer:
35 + 37
Step-by-step explanation:
if you try any other number like: 37 + 39 = 76 that doesn't work well because its higher that 75.
