4 0
So first subtract 20 from both sides of the equation.
3x-4=35
now add 4 to both sides.
3x=39
now divide both sides by
x=13

Solve the equation by factoring.<br> 3z2 + 3z – 6 = 0<br> z = 3 or z = 2
lana66690 [7]

Answer:

<u>3</u><u>z</u><u>^2 + 3z - 6 </u>=0

3

3 (z^2 + z -2) = 0

3(z+2)(z - 1) = 0

z + 2-2 = 0 - 2

z = -2

z - 1 + 1 = 0 + 1

z = 1

Step-by-step explanation:

  1. factor out the GCF (3) and divide everything by it, and then set it equal to zero.
  2. since you have a degree of 2, factor it into two binomials that start with the square root of the first term and end with the square root of the second term.
  3. 3=0 is extraneous solution so we leave it, then we set each binomial equal to zero to solve for z.

note: your solutions is based on the degree or the exponent of the polynomial or the function.

Find the second derivative y= x^2lnx
Dimas [21]
First we use product rule
y=x^2lnx
dy/dx = x^2 d/dx (lnx) + lnx d/dx (x^2)
dy/dx = x^2 (1/x) + lnx (2x)
dy/dx = x + 2xlnx

now taking second derivative:
d2y/dx2 = 1 + 2[x (1/x) + lnx (1)]
d2y/dx2 = 1 + 2[1+lnx]
         1+2+2lnx
         3+2lnx is the answer
