Solve for x. |4x - 5| > 7

see explanation

Step-by-step explanation:

Inequalities of the type | x | > a have solutions in the form

x < - a OR x > a thus

4x - 5 < - 7 ( add 5 to both sides )

4x < - 2 ( divide both sides by 4 )

x < -

OR

4x - 5 > 7 ( add 5 to both sides )

4x > 12 ( divide both sides by 4 )

x > 3

Solution is x < - or x > 3

This can be expressed in interval notation as

(- ∞, - ) u (3, ∞ )

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400
