Step-by-step explanation:

lenght = x + 8

width = x

perimeter = 2(x + 8) + 2(x) \\ 96= 2x + 16 + 2x \\ 4x = 96 - 16 \\ x =  \frac{80}{4}  \\ x = 20

then

Lenght = x + 8 = 20 + 8 = 28

Width = x = 20

Step-by-step explanation:

L=8+2W

P=2L+2W

P=2(8+2W)+2W

P=16+4W+2W

P=16+6W

P=96

96=16-6W

80=6W

W=13.3333

An equation is written where the sum of two 3-digit numbers is a 3-digit number N. Each digit, 1 through 9, is used exactly once
Sindrei [870]
We can start with:
x + y = N
where
x is the first 3 digit number
y is the second 3 digit number

In order to get the maximum value of N, the digits used must 9,8,7,6,5,4
To maximize, 9 and 8 must be added. This can only happen if 9 is the first digit of the first number and 8 is the first digit of the second number. The same idea is applied to the other digits. So
x must be 975 and
y must be 864
N = 975 + 864 = 1839
