Answer:
1.39 m
Step-by-step explanation:
sin 63 = x/13.5 (x = CD)
sin 52 = x/13.5 (x=AC)
take the difference between the two
So, x^2 + 14 x + 49 - 4 = 0;
Then, we use the formula ( a + b )^2 = a^2 + 2ab + b^2;
We have ( x + 7 )^2 - 2^2 = 0;
Then, ( x + 7 )^2 - 2^2 = 0;
We use the formula a^2 - b^2 = ( a - b)( a + b );
We obtain ( x + 5 )( x + 9) = 0;
Then, x + 5 = 0;
x = -5;
x + 9 = 0;
x = - 9;
-5 and - 9 are the zeros of the quadratic function.

Answer:
there would be 67.2 in 2 containers
Step-by-step explanation:
if you take 672 and divide that by 5 you get 134.4 so if you take that number and divide it by 2 you would get 67.2 hope this helps
