Answer:
B.
Step-by-step explanation:
The value of g(x) = 2[f(x)]² - 1 is g(x) = 8x² + 8x + 1
<h3>How to find a function?</h3>
f(x) = 2x+1
Find
g(x) = 2[f(x)]² - 1
Hence,
g(x) = 2[2x + 1]² - 1
g(x) = 2[4x² + 4x + 1] - 1
g(x) = 8x² + 8x + 2 - 1
g(x) = 8x² + 8x + 1

Answer:
x = 48°
Step-by-step explanation:
<u />
<u>Complementary angles</u>
Angles that sum to 90°.
<u />
<u>Vertical Angle Theorem</u>
When two straight lines intersect, the vertical angles are congruent (equal).
Therefore, angle x is equal to the angle that is complementary to 42°.
To find x, subtract 42° from 90°:
⇒ x = 90° - 42°
⇒ x = 48°
