One-half of a number plus six will equal 20.
Solving:
1/2x + 6 = 20
-6 -6
1/2x = 14
*2/1 *2/1
x = 28 <--Answer to problem
48x-56y+12! Hope that helps
Step-by-step explanation:
dy/dx
= d/dx [x / (1 - x²)]
= [(1 - x²)(1) - (x)(-2x)] / (1 - x²)²
= (1 + x²) / (1 - x²)².
When dy/dx = 1, (1 + x²) / (1 - x²)² = 1.
=> 1 + x² = 1 - x²
=> 2x² = 0, x = 0.
Also when x = 0, y = (0) / [1 - (0)²] = 0.
Hence the coodinates is (0, 0).
3 boxes times 40 = 120 + 3 = 143
or 3 boxes times 43 = 129
Answer:
Length: 10 inches
Step-by-step explanation:
Because we know that the total perimeter of the rectangle is 40, we can just divide the perimeter by the width, which gets us 10 inches (length).
40/4=10 inches
