Use the formula,

I = Prt

P = Principal amount = 400

I = interest = 18

r = annual rate

t = time in years = 9/12 = 3/4

so,

18 = 400*r*3/4

r = 0.06

so the annual interest rate is 0.06 or 6%

FIRST TO ANSWER GETS BRAINLIEST!

For this case we have the following expression:

(4m + 3) + 5m =

We eliminate the parentheses:

4m + 3 + 5m =

We add similar terms:

4m + 5m + 3 =\\9m + 3

Thus, we have a linear expression (the exponent of the variable term is 1).

The expression consists of two algebraic terms, so it is a binomial.

We have that algebraic terms are integers when they have no literal denominator.

9m: Positive, whole, rational term.

3: Constant term.

Answer:

9m: Positive, whole, rational term.

3: Constant term.
