The answer is minus 666 that’s the answer byee
45 because 1set equals 3 push ups and she did ten sets so 10sets equal 30 push ups and then her coach asked her to do 15 more so 30 plus 15 equals 45 so she did 45 push ups that day!
All you have to do is divide 500 by 3.
500 divided by 3 is 166.666667
I hope this helps:)
X^2 - 6x = 20
x^2 - 6x + 9 = 20 + 9
(x - 3)^2 = 29
x - 3 = (+-) sqrt 29
x = 3 (+-) sqrt 29
x = 3 (+-) 5.39
x = 3 + 5.39 = 8.39 <=
x = 3 - 5.39 = - 2.39 <=
The perimeter is 32 cm.
The length is 10, and the width is 6. (10x2) + (6x2) = 32
