Answer:
The length and width of the rectangle are 20 inches and 17 inches .
Step-by-step explanation:
Formula
Area of a rectangle = Length × Breadth
As given
The width of a rectangle is 3 inches less than its length. The area of the rectangle is 340 square inches.
Let us assume that the length is denoted by l.
Thus
Breadth = l - 3
Put in the above formula
340 = l × (l - 3)
340 = l² - 3l
l² - 3l - 340 = 0
l² - 20l + 17l - 340 = 0
l(l-20) + 17 (l-20) = 0
(l - 20) ( l+ 17) = 0
l = 20
l = -17 (This valueof length is neglected because length cannot be negative.)
As l = 20 inches
Breadth = 20 - 3
= 17 inches
Therefore the length and width of the rectangle are 20 inches and 17 inches .
Answer:
(-60x - 90x + 8) / (3x^2 + 2)^4 or you could write it as
2( -30x - 45x + 4) / (3x^2 + 2)^4
Step-by-step explanation:
Using the Quotient rule:
d(u/v) = (vdu - udv) / v^2
We have:
[3x^2 + 2)^3 * 4 - (4x + 5) * 3 (3x^2 + 2)^2 * 6x] / (3x^2 + 2)^6
= 4(3x^2 + 2) - 18x(4x + 5) / (3x^2 + 2)^4
= (12x^2 + 8 - 72x^2 - 90x ) / (3x^2 + 2)^4
= (-60x - 90x + 8) / (3x^2 + 2)^4
= 2( -30x - 45x + 4) / (3x^2 + 2)^4
Answer:
I folded a chainring on my bike so instead of a circle it was more parabolic and it was semi symetric due to the amount of teeth on each side of it.
