Step-by-step explanation:

For this exercise you need to remember the multiplication of signs:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-$

1. Given:

$(4x + 2.2)(3x - 5)$

Apply the Distributive property:

$=12x^2+6.6x-20x-11$

Add the like terms:

$=12x^2-13.4x-11$

You can idenfity that:

- Degree: 2

- Number of terms: 3

2. Given:

$(-304 +503 - 12) + (7x^3 - 25 + 6)$

Add the like terms:

$=187 + 7x^3 - 25 + 6=7x^3+168$

You can idenfity that:

- Degree: 3

- Number of terms: 2

3. Given:

$(3x^2 - 3)(3x^2 + 3)$

Apply Distributive property:

Solve Ixl<13{(-13, 13}<br> {xl-13 [XIX<-13 or x 13)

zmey [24]

Answer:

-13 < X < 13

Step-by-step explanation:

It is given |X| < 13.

Note that we have: |x| < a, for any real number 'a', then it equals:

-a < X < a.

So, in this case, |X| < 13 should be equal to -13 < X < 13.

Hence, the answer.
