Answer:
x=-3.5
Step-by-step explanation:
14/-4 = -3.5
Answer: 22
explanation: the easiest way is to separate one of the diagonals into a triangle and use the pythagorean theorem.
a^2 + b^2 = c^2
4^2 + 3^3 = c^2
16 + 9 = c^2
25 = c^2
5 = c
you now know that both of the diagonals have a length of 5.
by counting the units on the two straight, you know that their length is 6.
6 + 6 + 5 + 5 = 22
Let x be the unknown number. Then we have 18+x/4=x which is the same as (3/4)x=18 or x=24.
