5(2x + 3y) - 4(3x - 5y)
5(2x) + 5(3y) - 4(3x) + 4(5y)
(10x + 15y) + (-12x + 20y)
(10x - 12x) + (15y + 20y)
-2x + 35y
The answer is b because i just solves it
For this problem, the total length of fencing is equivalent to the perimeter of a rectangle. The formula for the perimeter of a rectangle is written below:
P = 2L + 2W
where L and W are the length and width dimensions
From the relationship described,
P = 350,350 ft
W = 2/3 L
Substituting this to the perimeter equation:
350,350 = 2L + 2(2/3 L)
Solving for L,
L = 105,105 ft
W = (2/3)(L) = (2/3)(105,105) = 70,070 ft
The expression to represent this would be (m-18)/k.
We first subtract the 18 beads she used in her mother's bracelet from her beginning number, m. We then divide our result by k, the number of bracelets she made for her friends.
