halo ka tolong dong bantu 3-10 serta pake cara nya ya terimakasih boleh pake keterangan soalnya kurang ngerti makasi

Call the first school "School A." Call the rest of the schools "School B, School C, School D, and school E."
The ratio of boys to girls in school A is 1:2. Therefore:
2 1 ​ = x 16 ​
Solving for x in that equation gives us 32 girls. Therefore, School A sent 48 kids in all.
School B - E have the same numbers. Therefore, the number of students sent to the conference is 48 x 5 . Therefore, 240 kids attended the conference.
Hope that helped!

In total, 240 students were sent to the conference, with each of the five schools sending 48 students. School A contributed 48 students (16 boys and 32 girls), while the remaining four schools sent only girls. Since all schools sent the same number of students, the calculation shows a total of 240 students attending.

Jawaban:1. (√6 + 5)(√6 + 3)- = (√6 * √6) + (3 * √6) + (5 * √6) + (5 * 3)- = 6 + 3√6 + 5√6 + 15- = 21 + 8√6   2. (2√6 - 2)(√6 + 5)- = (2√6 * √6) + (2√6 * 5) + (-2 * √6) + (-2 * 5)- = 12 + 10√6 - 2√6 - 10- = 2 + 8√6   3. (3√8 - √3)(3√5 - √2)- = (3√8 * 3√5) + (3√8 * -√2) + (-√3 * 3√5) + (-√3 * -√2)- = 9√40 - 3√16 - 3√15 + √6- = 9√(4*10) - 3(4) - 3√15 + √6- = 18√10 - 12 - 3√15 + √6   4. (√12 + 7)(√12 - 7)- Ini adalah bentuk (a + b)(a - b) = a² - b²- = (√12)² - (7)²- = 12 - 49- = -37   5. (√8 - √5)(√8 + √5)- Ini juga bentuk (a - b)(a + b) = a² - b²- = (√8)² - (√5)²- = 8 - 5- = 3   6. (3√7 + 9)(3√7 - 9)- Ini adalah bentuk (a + b)(a - b) = a² - b²- = (3√7)² - (9)²- = 9 * 7 - 81- = 63 - 81- = -18   7. (6√3 - √8)(6√3 + √8)- Ini adalah bentuk (a - b)(a + b) = a² - b²- = (6√3)² - (√8)²- = 36 * 3 - 8- = 108 - 8- = 100   8. (10 - 4√6)(10 + 4√6)- Ini adalah bentuk (a - b)(a + b) = a² - b²- = (10)² - (4√6)²- = 100 - 16 * 6- = 100 - 96- = 4
