Ответ:
length=3width-5
(2(x))+(2(3x-5)=46
2x+6x+10=46
8x=56
x=7
width=7 length=16
Ответ:
w = 7
l = 3w-5
2l + 2w = 46
lets substitute the value of length
2(3w-5)+2w
6w-10+2w
6w+2w = 8w
8w-10 = 46
add 10 to both sides to cancel out the -10 on the left side.
8w = 56
56/8 = 7
w = 7
hope this helps and hope it is correct
