Answer:
-6
Step-by-step explanation: 6 6 15 40
f(x) = –2 – 4, find f(4)
since there is NO x term in the function for ANY x
f(4) = –2 – 4 = -6
f(any x) = –2 – 4, find f(-∞ = x = ∞)
= -6

Step-by-step explanation:
Multiply all of the terms together
Answer:
r = 6
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
PR² = PQ² + QR² , substitute values
(r + 4)² = r² + 8²
r² + 8r + 16 = r² + 64 ( subtract r² from both sides )
8r + 16 = 64 ( subtract 16 from both sides )
8r = 48 ( divide both sides by 8 )
r = 6
