Answer:
x = 5
Step-by-step explanation:
Since these are similar triangles all you need to do is figure out how much "x" has gotten smaller.
First take the line DE length (16) and divide it by line BC (8)
16 / 8 = 2
Now divide line BD by 2
10 / 2 = 5
x = 5

Answer:
is not polynomial.
Step-by-step explanation:
We have been given an expression . We are asked to determine whether the given expression is polynomial or not.
We know that a polynomial expression is in form , where n is a non-negative number and a is a constant.
Upon looking at our given expression, we can see that it has a negative exponent.
Since exponents in polynomials must be positive, therefore, our given expression is not a polynomial.
