What is 4.5, 3.25, 2, 0.75 increasing or decreasing by

decreasing by 1.25

Step-by-step explanation:

4.5-3.25=1.25, 3.25-2=1.25, etc.

deacreasing by 1.25

Step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
