P ≤ 6, first you divide both sides by 7 so you get p ≤ 6 bc 7/7 is 0 and 42/7 is 6
Find cos using trig identities:
Therefore
Sub in tan x = 3, (Note that x is in 3rd quadrant, cos x < 0)
Finally, sub into Half-angle formula:(Note x/2 is in 2nd quadrant, tan x<0)
Answer: if the iguana is five feet it would be 60 inches
Answer:
-2r^3+4r^2+12r-4
Step-by-step explanation:
6r^3-2r^2+12r-4-8r^3+6r^2
(6r^3-8r^3)+(-2r^2+6r^2)+12r-4
simplify
-2r^3+4r^3+12r-4
Z/1 = 32/1
8 = 8/1
8/1 : 1/4 = 8/1 • 4/1 = 32
