Nana's age: 10 years
Step-by-step explanation:
Here we call:
J = Jennifer's age
L = Laurel's age
N = Nana's age
We have the following information:
- Jennifer is twice as old as laurel, so
J = 2L (1)
- Laurel is 4 years younger than Nana, so
L = N - 4 (2)
- Nana is 2 years younger than Jennifer, so
N = J -2 (3)
Substituting (2) into (1),
J = 2(N-4) = 2N - 8
And substituting this into (3) and solving for J, we find Nana's age:
N = (2N-8) - 2
N = 2N - 10
N = 10
Which means that Jennifer's age is:
J = N + 2 = 12
And Laurel's age is
L = J/2 = 6

Answer:
Simplifying
5x + 12 = -13
Reorder the terms:
12 + 5x = -13
Solving
12 + 5x = -13
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-12' to each side of the equation.
12 + -12 + 5x = -13 + -12
Combine like terms: 12 + -12 = 0
0 + 5x = -13 + -12
5x = -13 + -12
Combine like terms: -13 + -12 = -25
5x = -25
Divide each side by '5'.
x = -5
Simplifying
x = -5

so its 4.
I HOPE ITS RIGHT, IM 11
Since all sides of a square are equal all sides of the square would 44cm
To find the area it’s multiply the base and height: 44*44=1936cm^2
So your answer would be 1936cm^2
I hope this helps :)
