Answer: the height of the television screen is 20 inches
Step-by-step explanation:
The diagram of the rectangular television screen is shown in the attached photo. The rectangle is labelled as ABCD. The diagonal forms a right angle triangle, ABC. This means that angle B is 90 degrees. The height it labelled as h. To determine h, we will apply Pythagoras theorem. Pythagoras theorem is expressed as
Hypotenuse ^2 = opposite ^2 + adjacent ^2
From the diagram,
hypotenuse = 29 inches
Adjacent = 21 inches. Therefore,
29^2 = 21^2 + h^2
h^2 = 29^2 - 21^2 = 841 - 441
h = √400
h = 20 inches

Answer:
-(14 - 7x); 7(x - 2); 3x - 14 + 4x
Step-by-step explanation:
for -(14 - 7x) when the negative is distributed you get -14 + 7x which is still 7x - 14
for 7(x - 2) when multiplied in you get 7x - 14
for 3x - 14 + 4x when added together you get 7x - 14
