C I think because if you multiply 5 to everything you would get c
It is 1/6 or .16 I used Photomath
Answer:
c(x) = –8x^2 + 3x – 5 is a quadratic
Step-by-step explanation:
A quadratic function involves the 2nd power of x: x^2, and may (or may not) involve the 1st and zeroth power of x.
a(x) = -2x^3 is not a quadratic because of that exponent 3; in a quadratic, the highest power is always 2.
b(x) = 5x^3 + 8x^2 + 3 is not a quadratic for the same reason that a(x) is not a quadratic.
c(x) = –8x^2 + 3x – 5 is a quadratic: the highest power of x is x^2, the other powers are x^1 and x^0.
Aec= 40
Explanation because it’s a 90 degree angle and dea = 50
So 90-50=40
Plea give me Brainiest
Since they've already told us what triangles are congruent, all we have to do is match up the correct letters.
By CPCTC, angle N is congruent to angle B.
Hope this helps!
