Answer is 1/2 ln (x^2+1) + 2 tan ^-1 (x) +c
in order to do this first say (x/x^2+1)+ 2/(x^2+1)
we already know that 1/x^2+1 equal tan^-1 (x)
for the first part you need to say u=x^2+1 and solve it by substitution
I hope this helps..let me know if you need more explanation
Answer: $142.5
Step-by-step explanation: If the price is being marked up by 50%, you take 50% or half of the original price of $95, which is 47.5, and add it to your original price.
95 + 47.5 = 142.5
Answer:
width = 3.5 feet length = 8 feet.
Step-by-step explanation:
W=x
L=2x+1
Area=(2x+1)x=28
2x^2+x=28
2x^2+x-28=0
(2x-7)(x+4)=0
x=3.5,-4. It should be a positive number so W=3.5
2x+1=8 2x3.5=7 7+1 = 8 L=8
That area is 28 ft^2
width is 3.5 feet and length is 8 feet.
