5( 4n-3) also could someone explain to me how to do similar equations

Simplify.

Distribute 5 to all terms within the parenthesis

5(4n) = 20n

5(-3) = -15

20n - 15 is your answer

hope this helps

What you do is to follow PEMDAS. Combine like terms, and distribute the outside term (that is connected to the parenthesis) to all terms within the parenthesis.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

∡ eia and ∡ kij are congruent
