Answer:
Step-by-step explanation:
Work done is given by
, where d = length of cable and w = weight of cable.
Here, d = 175 ft and w = 3 lb/ft
Now, 
![work \ done= 3\left [175x-\frac{x^2}{2} \right ]_0^{175}](https://tex.z-dn.net/?f=work%20%5C%20done%3D%203%5Cleft%20%5B175x-%5Cfrac%7Bx%5E2%7D%7B2%7D%20%20%5Cright%20%5D_0%5E%7B175%7D)
![work \ done= 3\left [175^2-\frac{175^2}{2} \right ]](https://tex.z-dn.net/?f=work%20%5C%20done%3D%203%5Cleft%20%5B175%5E2-%5Cfrac%7B175%5E2%7D%7B2%7D%20%20%5Cright%20%5D)
32, 38, so on. So its +4 then +8 then +12 +16 +20....
Steps to solve:
2(n + 3) = 2n + 3
~Distribute left side
2n + 6 = 2n + 3
~Subtract 6 to both sides
2n = 2n - 3
~Subtract 2n to both sides
n = -3
Best of Luck!
Answer:
Sum of the interior angles of the triangle is 180°.
According to the above problem,
<h3><u>y=26</u><u>°</u> is the right answer.</h3>
Answer:
Step-by-step explanation:
3x + 20
You will need to find out what x represents by doing that you add 80+60 which equals 140 now you know what your missing
3 times what + 20 equals 140
40×3=120+20=140
Your answer would be 3•40+20=140
