minute. Gear Y has 24 cogs and gear
Z has 6 cogs
How fast and in which direction does
gear Z turn?

5 * 3 + 5 * 4 = 35

Step-by-step explanation:

Given  :  5 x (3 +4).

To find : The distributive property to write an expression equivalent.

Solution : We have given 5 x (3 +4).

Using Distributing property : a ( b +c ) = a *b + a* c .

5 x (3 +4) = 5 * 3 + 5 * 4 .

5 * 3 + 5 * 4 = 15 + 20 = 35 .

Therefore, 5 * 3 + 5 * 4 = 35
