Answer:
The additive inverse is equal to 
Step-by-step explanation:
we know that
Two polynomials area additive inverses if they are opposites of each other
we have

To find the additive inverse multiply the polynomial by -1

In the smallest of the three triangles (with sides
) we have

In the second-largest triangle (with sides
), the length of the missing side is
. Then in the largest triangle (with sides
), we have



Equivalently, we have

In turn, we find

Answer:
4
Step-by-step explanation:
Assuming that this is a right triangle, then (50 in)^2 = b^2 + (14 in)^2, according to the Pythagorean Theorem.
Then 196 in^2 + b^2 = 2500 in^2. Solving for b^2:
b^2 = (2500-196) in^2, and so b = +48 inches (answer)
