4g + 7g2 - 9 is a (select)
(select)

an equation.

Step-by-step explanation:

a statement of the equality of two mathematical expressions.

Quadratic trinomial

The largest exponent is 2, so the degree is 2. This makes the polynomial a quadratic.

It is also a trinomial as there are 3 terms. Each term is separated by a plus or a minus. It might help to think of 4g+7g^2-9 as 4g+7g^2+(-9).

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
