Answer:
1, 2, 3, 5
Step-by-step explanation:
I took the quiz
Let the number be xy ,
xy = 10x + y. when reversed = yx = 10y + x
x = 2y ........(a)
10x + y + 10y + x = 66.........(b)
10(2y) + y + 10y + 2y = 66
20y + y + 10y + 2y = 66
33y = 66
y = 66/33
y = 2
x = 2y = 2*2 = 4
Recall the original number is xy = 42.
Not sure what 14 is asking?
15 would be 16.
The square root of width squared plus length squared equals the diagonal.
So if you just change the order of the equation you can find the length.
Double check it by doing it both ways to see if your answer is right.
(x + 3) (x + 2) = 0
To solve it, the most appropriate technique is:
1.) zero product property
The solutions are:
(x + 3) = 0
x = -3
(x + 2) = 0
x = -2
x² + 6 = 31
To solve it, the most appropriate technique is:
2.) square root property
x² = 31-6
x² = 25
x = +/- root (25)
x = +/- 5
The solutions are:
x = 5
x = -5
Answer:
24 is the whole desposited. unless you are not counting the money she spent to open it. then it would be $23.50
