No.
3(7 + 2) = 3x7 + 3x2 is an example of the distributive law.The distributive law connects multiplication and addition.

y = -1/(3x7 + 2x - 9)y = -(3x7 + 2x - 9)-1y' = -(-1)(3x7 + 2x - 9)-2(3x7 + 2x - 9)'y' = (3x7 + 2x - 9)-2(21x6 + 2)y' = (21x6 + 2)/(3x7 + 2x - 9)2
It is: 5+(3*7) = 26
Do you mean what is 8x + 9x (=17x) ?
3x7 = 21
The answer will depend on what x9 is equal to..
Short answer: 42 Longer answer: Convert everything into 9ths. You get 4x9 (36) plus 2/3 x9 (6)
We don't know and can't calculate it, until we're given the value of 'x'.
