8. The width (w) of a rectangular lawn is 3 metres less than half its length(). The perimeter is 42 metres. 1. Show that w+l = 21
ii. Write an equation for the width (w) in terms of the length (1)
iii. Calculate, in metres, the width (w) of the lawn

step-by-step explanation:

i am not sure sorry : c

idk

step-by-step explanation:

idk

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

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.
