Answer:
Step-by-step explanation:
The television takes the shape of a rectangle whose width is 25 inches and whose height is 18 inches. To determine the length of the diagonal, we will apply Pythagoras theorem. It states that
Hypotenuse^2 = opposite^2 + adjacent^2
From the given information,
Adjacent side = 25 inches
Opposite side = 18 inches
Diagonal = hypotenuse.
Therefore
Diagonal^2 = 25^2 + 18^2
Diagonal^2 = 625 + 324 = 949
Take square roots of both sides of the equation, it becomes
Diagonal = √949 = 30.805 inches
Approximately 30.8 inches to the nearest tenth.
Subtract 27 from 36 = 9
9/36 = 0.25
To turn a decimal into a percent multiply by 100

Answer:
A-(2x+5)
Step-by-step explanation:
(2x+5)(2x+5)=4x^2+10x+10x+25 when you do FOIL, so that is the correct answer.
2*4^2+3(6/2)=Y
2*16+3(3)=Y
32+9=Y
41=Y
