simplify (5w-15)2.1

Solution

simplify

(5 w - 15) 2.1

10.5 w - 31.5

Solution steps

(5 w - 15) \cdot 2.1

= 2.1 (5 w - 15)

Apply the distributive law:

a (b - c) = ab - a c

2.1 (5 w - 15) = 2.1 \cdot 5 w - 2.1 \cdot 15

= 2.1 \cdot 5 w - 2.1 \cdot 15

Simplify

2.1 \cdot 5 w - 2.1 \cdot 15 : 10.5 w - 31.5

= 10.5 w - 31.5
