It is: 5+(3*7) = 26
3x7 = 21
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
if you do 3x7 and you need to get 6x7 then just do it 2 times
We don't know and can't calculate it, until we're given the value of 'x'.
3x7
3(7 + 2) = 3x7 + 3x2 is an example of the distributive law.The distributive law connects multiplication and addition.
2x7 = 14 x7 = 7 3x7 = 3*7 = 21
