Answer:
33i - 12
Step-by-step explanation:
![8i - (12 - 4i) + 7 \sqrt{ - 9} \\ = 8i - 12 + 4i + 7 \sqrt{9 \times ( - 1)} \\ = 12i - 12 + 7 \times 3 \sqrt{ - 1} \\ = 12i - 12 + 21i \: \: ( \because \sqrt{ - 1} = i)\\ = 12i + 21i - 12 \\ \therefore \red{ \bold{8i - (12 - 4i) + 7 \sqrt{ - 9} }= \purple{ \bold{33i - 12}}}](https://tex.z-dn.net/?f=8i%20-%20%2812%20-%204i%29%20%2B%207%20%5Csqrt%7B%20-%209%7D%20%20%20%5C%5C%20%20%3D%208i%20-%2012%20%20%2B%204i%20%2B%207%20%5Csqrt%7B9%20%20%5Ctimes%20%28%20-%201%29%7D%20%20%5C%5C%20%3D%2012i%20-%2012%20%2B%207%20%5Ctimes%203%20%5Csqrt%7B%20-%201%7D%20%20%5C%5C%20%3D%2012i%20-%2012%20%2B%2021i%20%20%5C%3A%20%20%5C%3A%20%28%20%5Cbecause%20%20%5Csqrt%7B%20-%201%7D%20%3D%20i%29%5C%5C%20%20%3D%2012i%20%2B%2021i%20-%2012%20%5C%5C%20%20%20%5Ctherefore%20%5Cred%7B%20%5Cbold%7B8i%20-%20%2812%20-%204i%29%20%2B%207%20%5Csqrt%7B%20-%209%7D%20%7D%3D%20%20%5Cpurple%7B%20%5Cbold%7B33i%20-%2012%7D%7D%7D)

Answer:![\frac{15+8a}{15a}](https://tex.z-dn.net/?f=%5Cfrac%7B15%2B8a%7D%7B15a%7D)
Step-by-step explanation:
![=\frac{1}{3a} +\frac{3}{5} -\frac{1}{15}+ \frac{2}{3a} \\= \frac{1}{3a} +\frac{8}{15} +\frac{2}{3a} \\=\frac{5+8a+10}{15a} \\=\frac{15+8a}{15a}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B3a%7D%20%2B%5Cfrac%7B3%7D%7B5%7D%20-%5Cfrac%7B1%7D%7B15%7D%2B%20%5Cfrac%7B2%7D%7B3a%7D%20%5C%5C%3D%20%5Cfrac%7B1%7D%7B3a%7D%20%2B%5Cfrac%7B8%7D%7B15%7D%20%2B%5Cfrac%7B2%7D%7B3a%7D%20%5C%5C%3D%5Cfrac%7B5%2B8a%2B10%7D%7B15a%7D%20%5C%5C%3D%5Cfrac%7B15%2B8a%7D%7B15a%7D)
Answer:
24
Step-by-step explanation:
The Pythagorean Theorem states that
where a and b are the legs in a right triangle and c is the hypotenuse. Therefore, just substitute the values a = 10 and c = 26 into the equation to get b = 24
