Answer:
-5x^2-2x
Step-by-step explanation:
When distributing, you multiply the term outside the brackets to all the terms in brackets.
If the term outside the bracket is negative, then when distributing/opening the brackets, the signs of the terms changes.
So in this prob. -x would multiply to both +5x and +2
-x*5x+-x*2
∴-5x^2-2x
Answer:
i x = 0
ii x = 5,9
iii y = 12
iv y = 0
Step-by-step explanation:
0 = 12x²/(x - 5)(x - 9)
0 = 12x²
0 = x²
x = 0
ii vertical asymptotes at x = 5, 9
asymptotes occur as either term (x - 5)(x - 9) approaches zero
iii horizontal asymptote y = 12
function essentially becomes 12(∞²)/∞² = 12(1) as x goes to ±∞
iv y = 0 where x = 0
Answer:
c.
Step-by-step explanation:
Since the patio is circular, the longest distance across a circle is the diameter = 2 * radius = 2 * 18 = 36ft
