Answer:
Step-by-step explanation:
<u>Given sides of a rectangle</u>
- Length: l =4 − 7(3x + 4y)
- Width: w = 3x(−2y)
<u>Perimeter of rectangle</u>
<u>Using the given values</u>
- P = 2( 4- 7(3x + 4y) + 3x(-2y)) =
- 2( 4 - 21x - 28y - 6xy) =
- 8 - 42x - 56y - 12xy
Difference between x and y is 25
lets say x is bigger
x-y=25
smaller is 1/6 of larger
y=x/6
sub x/6 for y in other equation
x-(x/6)=25
times both sides by 6
6x-x=150
5x=150
divide both sides by 5
x=30
y=x/6
y=30/6
y=5
the smaller number is 5
