Answer:
x = 8
Step-by-step explanation:
The complete question illustrates that the rectangle has sides ABCD and I've represented it as an attachment.
We have that:
AB = 3x
AD = 7x
The perimeter is calculated as:
Perimeter = 2 * (AB + AD)
Substitute values for AB, AD and Perimeter
160 = 2 * (3x + 7x)
160 = 2 * 10x
160 = 20x
Divide both sides by 20
8 = x
x = 8
We assume a linear system with 2 variables.
If the slopes are the same, and y-intercepts are different, there are 0 solutions.
If the slopes are different, there is 1 solution.
If the slopes are the same, and the y-intercepts are the same, there are ∞ solutions.
I think u take the number 16 and sutract it from 9 letters k/p. im not realy sure but i think that is right
hope im right
