5 times 4 equals 20. that's how
Let the width be x, the length is then 3x-10
Area of a rectangle is length times width: x(3x-10)=77 => 3x^2-10x-77=0
Factor this quadratic equation: (x-7)(3x+11)=0 =.x=7 or x=-11/3
width cannot be negative, so the only answer is x=7
width is 7m, length is 11m
Well, if any number is higher than '5' it turns one number more. So, here's a good rhyme to help you: "Five or more, up the score, Four or less, let it rest." The maximum number it could be would have to be '444' because it is not bigger than 445, which would turn to 500.
Answer:
Your net pay is

Step-by-step explanation:
All we have to do is add the deductions and then subtract them from what your earn.

By the angle difference formula for sines, we have:

By the angle sum formula for tangents, we have:

.
Rationalizing the denominator gives

as the final answer.
