Area of wall = 9 * 12 = 108 ft^2
Width of TV = x
Lenght = 2x
Diagonal of TV = 72 " = 6 ft
x^2+(2x)^2=6^2
x^2+4x^2=36
5x^2=35
x^2=36/5
x=sqrt(36/5)
Width = 2.68 ft.
Length = 2.68 * 5.36 = 14.36 ft^2
Area of wall - area of tv = 108 - 14.36 = 93.64 ft
Answer:
To find a number's square root, determine which two perfect squares the number lies between and estimate a fraction between those two perfect square roots. If it is a perfect square itself the square root can be arrived at precisely. If not, divide the number by one of the two closest square roots and average the result with the root. So there really isn't any answer to accurately do this that i'm aware of hope this helped!
Divide by 4 on both sides
Answer: A: 63
Step-by-step explanation:
How i remember doing this, is that I put the numbers in ascending order (as in lowest to highest) and once I'm done i look for the middle number, so you have 22,44,63,63,71,80,92 it helps me by looking at the numbers on the right and left, or put them in groups, so we have 22,44,63 (that's one group) then we have 71,80,92 (that's another group) so the only number we have left is 63 the middle number, that's your answer :]
