Lets solve all of these:-
#1
√361 = 361 · 2
?
√361 = 361 · 2
√361 = 19
361 · 2 = 722
19 ≠ 722
So this equation is not true
#2:-
√361 = 19²
?
√361 = 19²
√361= 19
19² = 19 · 19 = 361
19 ≠ 361
So this equation is not true
√361 = 361 ÷ 2
?
√361 = 361 ÷ 2
√361 = 19
361 ÷ 2 = 180.5
√361 ≠ 361 ÷ 2
So this equation is not true
√361 = √19²
√361 = 19
√19² = 19
19 = 19
SO the last one is right. Hope I helped ya!! xD

18 dollars would be the answer
Answer:

Step-by-step explanation:
By FOIL method, 
Answer:
The required value of x = 28
The required value of y = 32
Step-by-step explanation:
The given two equations are :

Now, we need to solve both the equations and find out the required values of both the unknowns x and y.
Solving equation (1) to obtain value of x. We have,

Solving equation (2) to obtain value of y. We have,

Hence, The required value of x = 28
And The value of y = 32
