Alternate exterior angles are the pair of angles that lie on the outer side of the two parallel lines but on either side of the transversal line. Illustration: ... Notice how the pairs of alternating exterior angles lie on opposite sides of the transversal but outside the two parallel lines.
Half-perimeter=length+width=width+3+width=43, 2×width=40 so width=20cm and length=23cm.
Answer:
(f o g)(x) = -2x² - x + 4
Step-by-step explanation:
f(x) = -x + 6
g(x) = 2x² + x + 2
To find (f o g)(x), you need put g(x) into f(x).
f(x) = -x + 6
(f o g)(x) = -(2x² + x + 2) + 6
(f o g)(x) = -2x² - x - 2 + 6
(f o g)(x) = -2x² - x + 4
