Can someone me with this? i don't understand how to solve it.
(3x^2a - 4y^az^3a)^2

(3x²ᵃ - 4yᵃz³ᵃ)² =

= 9x⁴ᵃ - 12x²ᵃyᵃz³ᵃ + 16y²ᵃz6ᵃ

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves

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.
