Answer:

The missing term is 1

Step-by-step explanation:

we have

2x^{2} +5x+3

Let

b-----> the missing term

we know that

2x^{2} +5x+3=(2x+3)(x+b)

solve for b

2x^{2} +5x+3=(2x+3)(x+b)\\ \\2x^{2} +5x+3=2x^{2} +2xb+3x+3b\\ \\2x^{2} +5x+3=2x^{2} +x(2b+3)+3b

Solve the system

2b+3=5 ------>b=1

Verify in the second equation

3b=3 ------> substitute the value of b ----> 3=3 --> is ok

therefore

2x^{2} +5x+3=(2x+3)(x+1)

(x + 1)

As:

(2x + 3)(x + 1) = 2x2 + 2x + 3x + 3

= 2x2 + 5x + 3

<em><u>explaination</u></em>

<u><em>\cos U = \frac{\text{adjacent}}{\text{hypotenuse}}=\frac{9.6}{x}</em></u>

<u><em>cosU= </em></u>

<u><em>hypotenuse</em></u>

Step-by-step explanation:

Let us assume that the total cost be x.

As given

Sophia pays $19.99 membership fee for an online music store.

If sophia purchases n songs for $0.99 each .

Than the expression becomes

Total cost = Membership fee + Cost of n songs

x = 19.99 + 0.99n

Here n represented the number of songs.
