Answer:
x-5
Step-by-step explanation:
So glad I could help! Here's why well we do definitely need to factor the area.
Because when factoring we have to expressions multiplying by each other.
A=LxW
Factored Expression=(x+5)(x-5)
See now it's LxW.

Answer:
4 packages of AA batteries
6 packages of AAA batteries.
Step-by-step explanation:
Let the number of packages of AA batteries bought be x
Let
the number of packages of AAA batteries bought be Y
He Brought 10 packages of AA and AAA
thus,
x+y = 10 equation 1
Given
The AA batteries are sold in packages of 6, it means one packet contains 6 batteries
Thus,
Total number of AA batteries in x packages = 6x
The AAA batteries are sold in packages of 8, it means one packet contains 8 batteries
Thus,
Total number of AAA batteries in y packages = 8y
Given total no. of batteries is 72
thus
6x + 8y = 72 equation 2
x+y = 10
y = 10-x ---using this in equation 2
6x + 8(10 - x) = 72
=> 6x + 80 - 8x = 72
=> -2x = 72-80 = -8
=> x = -8/-2 = 4
y = 10 -x = 10 -4 = 6
y = 6
Thus,
he bought 4 packages of AA batteries
6 packages of AAA batteries.

Answer:
A = 144 cm²
Step-by-step explanation:
Let the side of the square be x. Using Pythagoras theorem for square,
The area of the square is given by :
A = side²
Put values in the formula.
A = 12²
A = 144 cm²
So, the area of the square is equal 144 cm².
