When two terms are directly next two each other, they are being multiplied.
The answer is 5n
Answer:
Explanation:
Identity: sec2θ=1+tan2θ
sec2(π2−x)−1=1+tan2(π2−x)−1
=tan2(π2−x)
Identity: tan(π2−θ)=cotθ
=cot2x
The answer is the first one
(40+x)/2=60
40 +x = 120
x = 80
check :
40+80 = 120
120/2 = 60
so his second round needs to be 80 mph
Answer: 1/6
Invert 6/5 which becomes 5/6 and then multiply
3/15×5/6= 15/90
Which simplified becomes 1/6
