Answer: 2160 peeps don't wear glasses.
Step-by-step explanation: 180 x 12
The area = L*L=9 or 3*3=9
Which means that each sides length equals 3 if it is a perfect square.
Answer:
rounded to the nearest it would be 14%
Step-by-step explanation:
To find the dimensions you can just factor the equation...
x^2+4x-21
x^2-3x+7x-21
x(x-3)+7(x-3)
(x+7)(x-3) and this is equal to LW or WL
And note that x>3 for any possible solution.
Answer:
see below
Step-by-step explanation:
9 x 8 = (10 x 8) - ( blank x 8) =80 - blank = blank
We are replacing 9 with 10 minus something
9 = 10 -1
9 x 8 = (10 x 8) - ( 1 x 8)
80 - 8
72
