The dimensions such as length is 18 and width is 16 or length is 32 and width is 9 will produce an enclosed area of 288ft.
<h3>What is the dimension of length and width?</h3>
We know that,
P = l + 2w
50 = l + 2w
50 - 2w = l
A = l x w
288 = (50 - 2w)w
288 = 50w -2w²
2w² - 50w + 288
By dividing throughout by 2
w² - 25w + 144
This is in quadratic equation form.
By applying quadratic formula,
w = (-(-25) ±
) / 2
w = (-(-25) ± 7)/2
w1 = (-(-25) + 7)/2
w1 = (25 + 7) / 2
w1 = 16
w2 = (-(-25) - 7)/2
w2 = (25 - 7) / 2
w2 = 9
By substituting the values in eq1,
A = l x w
if w = 16
288 = l x 16
l = 288/16
l = 18
if w = 9
288 = l x 9
l = 288/9
l = 32
The dimensions will be length is 18 and width is 16 or length is 32 and width is 9.

Solving for x, we get

Answer:
-5/3 is the slope
Step-by-step explanation:
<u>Step 1: Solve for y to get y = mx + b</u>
5x + 3y = 12
5x + 3y - 5x = 12 - 5x
3y / 3 = (-5x + 12) / 3
y = -5/3x + 4
<u>Step 2: Determine where is slope or m in y = mx + b</u>
y = mx + b
y = -5/3x + 4
Answer: -5/3 is the slope
