Answer:

Option c.

Step-by-step explanation:

We have the set of real numbers greater than 8 and B the set of real numbers greater than 5 here:

A: x+2>10 ⇒ x>8

B: 2x > 10 ⇒ x>5

8∉A ; 8∈B

Note: We can see (graph) that the intervals are open, so the corresponding points do not belong to their respective sets.

vodka [1.7K]

The area of a window is 336 square inches if the window is 16 inches wide how long is the window
Ksenya-84 [330]
The formula for area is base times height, or height x width
So if the window is 16 inches wide then 336 divided by 16 equals the height
336 divided by 16 is 21.
Check
21 x 16 = 336
336 = 336
