Answer:

23 inches

Step-by-step explanation:

assuming that the desktop screen is a rectangle, then it's diagonal will form two right triangles.

by the Pythagorean theorem

{a}^{2}  +  {b}^{2}  =  {c}^{2}  \\  a = 14 \: and \: b = 18 \\ c  = the \: hypoteneuse

then

{14}^{2}  +  {18}^{2}  =  {c}^{2}  \\ 196 + 324 =  {c}^{2}  \\ 520 =  {c}^{2}  \\  \sqrt{ {c}^{2} }  =  \sqrt{520}  \\ c   \: \: is \: a pprox. \:  \: 22.8 in \\ c \:  \: rounded \: is \: 23in

How do you get the answer
lilavasa [31]

Answer:

(x + 2)(x - 4)

Step-by-step explanation:

Given the zeros of a function, say x = a and x = b, then

the factors are (x - a) and (x - b)

From the graph

The zeros are x = - 2 and x = 4, thus the factors are

(x - (- 2)) and (x - 4), that is (x + 2) and (x - 4)
