Answer:
D. -2(x + 7)
Step-by-step explanation:
To do part A and B, note that functions are distributive, meaning (h+t)(x) = h(x)+t(x) and (h•t)(x) = h(x)•t(x).
Giving:
A: (h+t)(x) = 2x - 5 + 6x + 4 = 8x - 1
B: (h•t)(x) = (2x - 5)•(6x + 4) = 12x^2 - 22x - 20
C: h[t(x)] = 2[t(x)] - 5 = 2(6x + 4) - 5 = 12x + 3
Answer:
m∠AOX = 40°
Step-by-step explanation:
If you look at <em>A</em> in the diagram, you can see the 40° beneath it, denoting that ∠A is 40°. When written as ∠AOX, this means "the angle that connects line A and line X at point O." This is to specify that angle A is ∠AOX and not m∠AOZ or m∠AOW or something. It's just a specification.
