Computer monitors are measured by their diagonals. If a monitor is advertised to be 19 in, what is the actual viewing area, assuming the screen is square? (Round to the nearest tenth.) 2. 361.0 in b. 90.25 in? c. 144.4 in? d. 180.5 in?​

468

step-by-step explanation:

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
