Mathematics
1 answer:
Anna007 [38]3 years ago
3 0

For this case we must simplify the following expression:

(2a ^ 3-5a) - (7a+ 3a ^ 2) =

By definition of the law of multiplication signs we have to:

- * + = -

Rewriting the expression we have:

2a ^ 3-5a-7a-3a ^ 2 =

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

2a ^ 3-3a ^ 2-12a

ANswer:

2a ^ 3-3a ^ 2-12a

A ski Gondola cabin can safely carry X number of people that are already 2/3 x people in the cabin went on another 15 or allowed
Strike441 [17]
30 people are already in the cabin.

If there’s 2/3 of the people that the cabin can carry, and 15 more can board, the 15 is the remaining 1/3, so to get the other 2/3 that we don’t know, you multiply 15 by 2, to get 30.

So all together, the cabin can carry 45 people.

Hope this helps!
