Answer:
3x+14≤50
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The surface area (A) of a sphere is calculated as
A = 4πr² ← r is the radius
here r = 2, hence
A = 4π × 2² = 4π × 4 = 16π units² → A
The second option!
4(3x + 5y + 1)
4 x 3x = 12x
4 x 5y = 20y
4 x 1 = 4
Which equals 12x + 20y + 4!
I hope this helped! Have a nice day! ~(^v^)~
