Which of these expressions can you simplify by combining like terms

Option 1.

Step-by-step explanation:

Like terms : Two terms are called like terms if they have same variables of same degree.

We need to find the expression that can be simplify by combining like terms .

It means we have to find the expression which contains like terms.

In option 1,

The given expression is

In this expression 5cd and -3dc are like terms. On combining like terms we get

So, this expression can simplify by combining like terms.

There are no like terms in other three expressions.

Therefore, the correct option is 1.

i'm sure goog can you get that answer

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
