PLEASE HELP NO LINKS AND NO BS If the tetrahedrons on your solid have edges that are 4 inches long, what is the area of one of
its triangular faces? Round your answer to the nearest hundredth. Show your work. (4 points: 3
points for the area, 1 point for work shown)

My solid is an octahedron with tetrahedrons

black lol

step-by-step explanation:

h

i can tell you jamal now has 3 cookies xd

tommy has 2.

this made me lol.

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:

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.

it is impossible.
