Answer:
<h2>(f – g)(x) = - x² + 4x + 6</h2>
Step-by-step explanation:
f(x) = 4x + 1
g(x) = x² – 5
To find (f – g)(x) subtract g(x) from f(x)
That's
(f – g)(x) = 4x + 1 - ( x² - 5)
Remove the bracket
(f – g)(x) = 4x + 1 - x² + 5
Group like terms
(f – g)(x) = - x² + 4x + 1 + 5
We have the final answer as
<h3>(f – g)(x) = - x² + 4x + 6</h3>

Step-by-step explanation:
Answer:
∠ 1 = 130°, ∠ 2 = 50°
Step-by-step explanation:
∠ 1 and 130° are alternate angles and congruent, so
∠ 1 = 130°
∠ 2 and 130° are same- side interior angles and are supplementary, so
∠ 2 + 130° = 180° ( subtract 130° from both sides )
∠ 2 = 50°

Anthony's Locker:
A = (x + 4)(x + 2)
= x^2 + 2x + 4x + 8
= x^2 + 6x + 8 ft^2 (H)
Anthony's Math Book:
A = (x + 6)(x - 3)
= x^2 - 3x + 6x - 18
= x^2 + 3x - 18 in^2 (V)
Anthony's Lunch Box:
A = (x - 9)(x - 2)
= x^2 - 2x - 9x + 18
= x^2 - 11x + 18 in^2 (L)
Anthony's Desk:
A = (x - 5)(x + 2)
= x^2 + 2x - 5x - 10
= x^2 - 3x - 10 ft^2 (M)
