He owes more than $36 because -$36 is the same thing as owing $36 but without the - so if his balance is less than $-36 then he owes more than $36
Answer: x ≈ 1.59688927, −1.60312387, −4.67045686, 4.69039614, 7.872914, −7.91513776, −10.89002194
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Simplify 2*cosx*(2x+30°) + √3=0

- Graph each side of the equation. The solution is the x-value of the point of intersection. x ≈ 1.59688927 , − 1.60312387 , − 4.67045686 , 4.69039614 , 7.872914 , − 7.91513776 , − 10.89002194
Answer:
21, 22, and 23
Step-by-step explanation:
Three consecutive natural numbers can be represented as n, n+1, and n+2.
The square of the smallest number would be
and its equal to the product of the other two (n+1)(n+2).
So the equation is
.
If n is 21 then the next numbers are 22 and 23.
