Step-by-step explanation:
LHS= sin 3x/sin x - cos 3x/cosx
Taking LCM,
<u>=</u><u>sin3xcosx- cos3xsinx</u>
sinxcosx
<u>=</u><u>sin(3x-x)</u>
sinxcosx
= <u>2sin2x</u>
2sinxcosx
=<u> </u><u>2sin2x</u><u> </u>
sin2x
=2
= RHS.
Proved.
Answer: n=p/2-m
Step-by-step explanation:
m=p/2-n (1)
Add n to both sides of the equation (1)
m+n=p/2-n+n => m+n=p/2 (2)
Subtract m from both sides of the equation (2)
m-m+n=p/2-m => n=p/2-m
Answer: 350,340,330,320,310,300,290,280,270,260,250,240.
Step-by-step explanation:
To solve this exercise you must keep on mind the following information:
1. By definition skip counting is about counting by a number which is not the number 1.
2. Skip counting by ten from 350 to 240 means that you need to subtract 10 to a number to find the other one.
3. Therefore, you must subtract 10 to 350 and then you need to do this over and over again until you get 240.
Answer:
x^2+14x+49 ( it could be polynomial because it has 3 terms and each term has a whole number and a coefficient)
Step-by-step explanation:
(x+7)^2
(x+7)(x+7)
x^2+7x+7x+49
x^2+14x+49
I am not sure it's a polynomial or not
