What is the solution ofx^2-1/x^2+5x+4< =0

Roots

x = -4.0205

x = 0.40245

x = -0.691 - 0.375*i

x = -0.691 + 0.375*i

Step-by-step explanation:

The equation is

x^2 - 1/x^2 + 5x + 4 = 0

Please see attached pictures below for

Answer with explanation:

The given Inequality is

The two inequalities have solution region

-4.02≤ x≤0.402 and , x>0.

Combining the two solution set, we get

→0<x≤0.402

This is required solution set of the Inequality given which is

  or  

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or  

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
