7. What is one of the best methods to multiply these binomials: (a +8)(x + 7) Distribute everything in one set of parentheses to the other set (FOIL or draw a BOX)
Factor out the GCF.
Use the quadratic formula.
Take the square root of both sides.

the answer is c)8

step-by-step explanaction:

i believe the answer is the polygon, heptagon.

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:

c > -10.55
