Step 1. You must write down/ underline all the numbers given in the problem.
Step2. Identify all the unknown variable such as x, y, a, b [those are the most common ones].
Step 3 Identify what sign of operation your working with... It can be +,-,×,÷.
Step 3 write down all your terms on the LHS of the equation.
Step 4. Equate all the constant on the RHS of the equation. If the constant was negative It would be positive and vic versa
Step. Solve your problem
Number of square numbers under 25= 1, 4, 9, 16 and 25
= 5 numbers
number of factors of 8 under 25 = 8, 16 and 24
= 3 numbers
number of good outcomes = 5 + 3
= 8 good outcomes
total outcomes = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 and 25.
= 25 outcomes
probability = good outcomes ÷ total outcomes
= 8/25
The probability that they number chosen is a square number or a factor of 8 is 8/25.

Answer:
b = 45.9 - c
Step-by-step explanation:
A scalene triangle has non of its sides equal.
Perimeter = 54.6
side a = 8.7 cm
side b = unknown
side c = unknown
Perimeter of a shape is sum of all its sides.
Perimeter = a + b + c
54.6 = 8.7 + b + c
Making b the subject
b = 54.6 - 8.7 - c
b = 45.9 - c
The value of b is (45.9 - c)
