![\dfrac{3}{\sqrt{13}-5}\bigg(\dfrac{\sqrt{13}+5}{\sqrt{13}+5}\bigg)\\\\\\=\dfrac{3(\sqrt{13}+5)}{13-25}\\\\\\=\dfrac{3(\sqrt{13}+5)}{-12}\\\\\\=\dfrac{\sqrt{13}+5}{-4}\\\\\\=\dfrac{-\sqrt{13}-5}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B%5Csqrt%7B13%7D-5%7D%5Cbigg%28%5Cdfrac%7B%5Csqrt%7B13%7D%2B5%7D%7B%5Csqrt%7B13%7D%2B5%7D%5Cbigg%29%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%7B3%28%5Csqrt%7B13%7D%2B5%29%7D%7B13-25%7D%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%7B3%28%5Csqrt%7B13%7D%2B5%29%7D%7B-12%7D%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%7B%5Csqrt%7B13%7D%2B5%7D%7B-4%7D%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%7B-%5Csqrt%7B13%7D-5%7D%7B4%7D)
Answer:
see below
Step-by-step explanation:
To check your solution , plug the value of k into the original equation
6(7k-10) =24
k=2
6(7*2-10) =24
6(14-10) =24
6(4) =24
24=24
The solution is correct
Answer Do it
Step-by-step explanation 165 divided by 100 =x times 43
In getting the area of and equilateral triangle, you must first consider that all of its sides are congruent and that is 3 inches, so the formula in getting the area is height form its base so in getting its height you must use the pythagorean theorem by dividing the triangle so the hypotenuse of it is 3 and the base of 1.5inches, so the height is 4.77 inches then the area is 7.15 sqr.inch
