Find the number of real number solutions for the equation. x2 + 5x + 7 = 0 0 2 1 cannot be determined

0 solution

Step-by-step explanation:

Given

Required

Find number of solutions;

The number of solutions can be determined via the value of determinants, D;

Such that

By comparing the general form of equation;

with

This gives

So;

becomes

The calculated value of D is less than 0;

This implies that has no real solution

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
