expand

(3, - 4) x (3, 9)

3 (3 \cdot 9,) x, - 4 (3 \cdot 9,) x

Solution steps

(3, - 4) x (3, 9)

= (3, - 4) (3 \cdot 9,) x

Apply the distributive law:

a (b - c) = ab - a c

a = x (3, 9), b = 3,, c = 4

= x (3, 9) \cdot 3, - x (3, 9) \cdot 4

= 3 (3 \cdot 9,) x, - 4 (3 \cdot 9,) x

\frac{3 ( 144 + 9 6 )}{125}

(x + 1) d y - [3 y]

\frac{5 ( 3 + 2 x )}{2 ( 5 - 4 x )}

\frac{x - 3 ( 2 y - z )}{2 x y}

3 (2 z - 10 = - 12)
