Answer:
84
59
Step-by-step explanation:
In other to have the same number of chayes in both rows and columns ;
If the Number of chairs per row = x ; then number of chairs per column = x
Then the total number of chairs needed = x * x = x²
Hence, if there are 5100 chairs ;
Number of chairs needed more ;
Take the square root of 5100 ;the round to the next whole number :
B.) For number of chairs to be removed ;
Take the square root of 5100 and round down to the whole number.
Hence,
A.) = √5100 = 71.414 = 72
72² - 5100 = 84
B.) 5100 = 71.414 = 71
5100 - 71² =
180-130=50
180-96=84
angles in a triangle add up to 180
50+84=134
180-134=46
x=46 degrees
Here x=3
so, putting 3 instead of x
This question is soooo easy
Step-by-step explanation:
(3x)^2+(5)^2+2.3x.5
9x^2+25+30x
