For domain 2x sqrt(2+x)>0
x>0,2+x>0,x>-2 combining 
we get x>2
f'(x)=[1/{2x sqrt(2+x)}][{2x/(2 sqrt(2+x))}+2 sqrt(2+x)]

Simplify the following fraction (9/16/1/4)-1/5
german

Answer: \frac{41}{20}

Step-by-step explanation:

The first step is to make the division of the fractions \frac{9}{16} and

\frac{1}{4}. To do this, you can flip the fraction \frac{1}{4} over and multiply the numerators and the denominators of the fractions. Then:

(\frac{\frac{9}{16}}{\frac{1}{4}})-\frac{1}{5}=(\frac{9}{16}*4)-\frac{1}{5}=\frac{36}{16}-\frac{1}{5}

Reduce the fraction \frac{36}{16}:

 =\frac{9}{4}-\frac{1}{5}

Now you can make the subtraction:  in this case the Least Common Denominator (LCD) will be the multiplication of the denominators.   Divide each denominator by the LCD and multiply this quotient by the corresponding numerator and then subtract the products. Therefore you get:

=\frac{45-4}{20}=\frac{41}{20}

2) Dada a equação x2 – 4x – 12, faça o que se pede.
alexandr1967 [171]

Answer:

a) x1 = 6 and x2 = -2

b) -2

Step-by-step explanation:

a)

To find the roots of the quadratic equation, we can use the Bhaskara's formula:

Delta = b^2 - 4ac

Delta = (-4)^2 - 4*1*(-12) = 64

sqrt(Delta) = 8

x1 = (-b + sqrt(Delta)) / 2a

x1 = (4 + 8) / 2

x1 = 6

x2 = (-b - sqrt(Delta)) / 2a

x2 = (4 - 8) / 2

x2 = -2

b)

The roots are 6 and -2, so the smaller root is -2
