What is the factored form of the expression over the complex numbers?

4x2+25y2

options-

a (2x+5iy)(2x−5iy)

b (2x−5y)(2x+5y)

c(2x+5iy)(2x+5iy)

d (2x−5iy)(2x−5iy)

⊂⊃⊂⊃ω

step-by-step explanation:

i hope this : )

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.

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

exactly you go it
