Given ; 2(10-13x)+9x=-34x+60
rewona [7]

Try comparing your solution with the following:

Solution:

2(10-13x)+9x=-34x+60\\(20-26x)+9x=-34x+60\\20-26x+9x=-34x+60\\20-17x=-34x+60\\20-60=-34x+17x\\-40=-17x\\x=\frac{40}{17}

Answer:

x=\frac{40}{17}

Check:

2[10-13(\frac{40}{17})]+9(\frac{40}{17})=-34(\frac{40}{17})+60\\-20=-20

What is the length of the hypotenuse of the trim angle ?
Ksju [112]

So for this, you'll be using the pythagorean theorem, which is leg^2+leg^2=hypotenuse^2 . In this case, 10 and 24 are the legs, and AB is the hypotenuse. Our equation will be 10^2+24^2=AB^2


Firstly, solve the exponents: 100+576=AB^2


Next, combine 100 and 576: 676=AB^2


And lastly, square root both sides to get 26=AB



And in short, Line AB is 26 ft, or the first option.
