You would combine like terms so the answer would be -7z-7
Answer:
D) cos^-1 (f/e)
Step-by-step explanation:
Since you only know two sides, DE = f, and DF = e, you need to use cosine to find the measure of ∠D.
Let x represent m∠D
cos x = f/e
To find x, take the inverse of cos, so:
cos^-1 (f/e) = x
Answer:
I believe it is 43 degrees.
Step-by-step explanation:
Answer:
f(x) = (x + 2)(x - 5)(x - 6)
Step-by-step explanation:
given the zeros of f(x) are x = a, x= b and x = c, then the factors are
(x - a), (x - b) and (x - c)
The function is then the product of the factors
f(x) = (x - a)(x - b)(x - c)
Here zeros are x = - 2, x = 5 and x = 6, thus the factors are
(x + 2), (x - 5) and (x - 6), so
f(x) = (x + 2)(x - 5)(x - 6) ← in factored form
X(2x + 10) is correct because of how it explained up there.
