Which expression has a negative value?

Atoy company is considering a cube or sphere-shaped container for packaging a new product. the height of the cube would equal the diameter of the sphere . compare the volume to surface area ratios of the containers. which packaging will be more efficient? for a sphere, sa =4πr²

25 ! the line of best fit is h = 5a + 86. predict the height at age 16. show your work.

The reflexive property of congruence lets you say that ∠pqr ≅
