<h2>Answer:</h2>

Using the distributive property, we can simplify the expression.

4 × 3 = 12

4 × \frac{1}{4} = 1

4 × (-\frac{1}{2}) = -2

Solve the inequality, enter it in interval notation , 6x+3&lt;8(8x+6)+3
garik1379 [7]

Answer:

The answer to your question is:    ( - 24 / 29, ∞ )

Step-by-step explanation:

                                             6x + 3 < 8 (8x + 6) + 3

                                             6x + 3 < 64x + 48 + 3

                                             6x + 3 < 64x + 51

                                             6x - 64x < 51 - 3

                                            - 58 x < 48

                                            x > - 48 / 58

                                            x > - 24 / 29

                                          ( - 24 / 29, ∞ )
