How many unique triangles can be formed with side lengths of 9 units and 6 units, and an angle of 40 degrees NOT formed by the intersection of the two sides? (not between them) How many triangles can be formed with the angle measures: 20, 70, and 90 degrees?

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
