The square root of 1444 is 38
(I used a calcultor)
Step-by-step explanation:
<em><u>a</u></em><em><u>)</u></em><em><u> </u></em><em><u>3</u></em><em><u>6</u></em><em><u> </u></em><em><u>on </u></em><em><u>section</u></em><em><u> </u></em><em><u>a</u></em><em><u> </u></em><em><u>qus</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>titik </u></em>
For the 40 hour week, they would be paid 40 multiplied by 9 which is 360. For the additional 3 hours they would be paid 18 dollars an hour, because its double.18 multiplied by 3 is 54. 360 + 54= 414. The answer is $414
So area is 168 sq ft
That means that length * width = 168 sq ft
Since length = 10 + 2 w
we get (10+2w)(w) = 168
Multiply it out and you get 2w^2 + 10w - 168 = 0
This is a quadratic equation. You can use the formula here, but i'll just tell you the answer
w = -12, or 7
since it can't equal -12 (ever heard of a barn with a length of -12?), you figure out the answer is 7.
If the width is 7, then the length is 10+2(7) = 24.
Have a nice day!
