34
because, 34 = 14 + (10 x 2)
and 34 = 24 + (10 x 1)
The picture is to blurry sorry
Answer:
Step-by-step explanation:
By geometric mean property:
By Pythagoras Theorem:
(xy)' + (2x)' + (3x^2)' = (4)'
y + xy' + 2 + 6x = 0
xy' = -y -2 -6x
y' = [-y -2 -6x] / x
Now solve y from the original equation and substitue
xy + 2x + 3x^2 = 4 => y = [-2x - 3x^2 + 4] / x
y' = [(-2x - 3x^2 +4) / x - 2 - 6x ] / x
y' = [-2x - 3x^2 + 4 -2x -6x^2 ] x^2 = [ -4x - 9x^2 + 4] / x^2 =
= [-9x^2 - 4x + 4] / x^2
First do any exponents: 3 to the 0 power would equal 1. Then multiply and divide in order: 2x1=2, 2/2=1. Then subtract: 23.6-1=22.6 :)
