What is the completely factored from of 9x2+24x+16
(3x+8)(3x+2)
(3x+4)(3x+4)
(9x+8)(x+2)
(9x+4)(x+4)

(3x+4)(3x+4) is factor of given expression.

B is correct.

Step-by-step explanation:

We are given an expression

Formula:

First we write each term as perfect square as formula.

Using formula , a=3x and b=4

Now we write same number two times.

Hence, (3x+4)(3x+4) is factor of given expression.

since both sides equal, there are infinitely many olutions.

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✌✌✌
