Middle right is your answer
25 is the answer for number 3
All triangles in this shape have same area as they have same base length and height length.
- area of triangle: 1/2 * base * height
Here the base is 4.2 cm and height is 2.5 cm for all the given triangles.
As a result, we can say that the area of 
A, B, C are equal.
The interval for the function to be negative will be (-∞<x<-7).
<h3>What is a function?</h3>
A function in mathematics set up a relatioship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.
Here we have a function:-
g(x) = ∛(x+6)
If we put the value of x lesser than 6 in the function we will always get a negative value so the interval will be:-
(-∞<x<-7).
Therefore interval for the function to be negative will be (-∞<x<-7).
