Simplify: `"3a"/8 + "4a"/5 - ("a"/2 + "2a"/5)`

Sum

`"3a"/8 + "4a"/5 - ("a"/2 + "2a"/5)`

`= ("15a" + "32a" - (20"a" + "16a"))/40` ...(LCM of 8,5,2 = 40)

`= ("47a" - "36a")/40 = "11a"/40`

Subtract: - 5a - 2b from b + 6c

Subtract: 4x² - 5x²y + y² from - 3y² + 5xy² - 7x² - 9x²y

The perimeter of a triangle is 14a² + 20a + 13. Two of its sides are 3a² + 5a + 1 and a² + 10a – 6. Find its third side.

If x = 4a² + b² - 6ab; y = 3b² - 2a² + 8ab and z = 6a² + 8b² - 6ab find: x - y - z
