Answer:
Length = 72 mm
Width = 46 mm
Ratio = 72:46 = 36:23
Step-by-step explanation:
72 and 36 both are divisible by 2. so when we divide them by two we get 36 and 23. we can divide both the sides only with the same number, but 36 and 23 have no common factors. so we leave it here and this is the answer.

Answer:
The answer to your question is:       (2a + 2b)²
Step-by-step explanation:
a² + b² = z
ab = y
Which is equivalent to 4z + 8y ?
Substitution 
                                      4(a² + b²) + 8(ab) 
Simplify                        4a² + 4b² + 8ab
Order                            4a² + 8ab + 4b²       It's a perfect square trynomial
Factorize                     (2a + 2b)²

Answer:
Incorrect.
Step-by-step explanation:
6 + x = 19
Plug in when x = 12
6 + 12 = 19
 18 = 19
It is incorrect, so 12 is not a solution.
