Answer:
-2.5
Step-by-step explanation:
The point is between -2 & -3
Since the sample is 1/25 the size and the size of the sample is 1m then:

x is the height of our container. we need to move 1/25 to the other side so we multiply both sides of the equation by 25.

On the right side of the equation, 1/25 cancels out with 25 since:

so we are left with the 25 x 1 on the left:

so the container is 25m; C.
Answer:
x=13/4 or -1
Step-by-step explanation:
factorize the fraction
(4x^2+4x)(-13x-13)
4x(x+1) -13(x+1)
(4x-13)(x+1)
x=13/4 or x=1
