So our original equations would be..
(a) perimeter in terms of y
(b) area in terms of y
*I'm actually not sure about b.. sorry*
(c) if perimeter = 28, find length
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
4m+2 (m-5)=26
4m+2m-10=26
6m-10=26
6m=36
M=6
Answer:
180
Step-by-step explanation:
to find the side of the smaller triangle you do 
x 
and get 3600. Then do
and get 60. Since the larger triangle is 3 times that size you do 3 x 60 and get 180.
