Answer x= 2
3x + 8 = 14
To solve subtract 8 from both sides to isolate x
3x = 6
Now divide both sides by 3 to solve for x
X = 2
Answer:
Mark is 30 and Teri 36
Step-by-step explanation:
I suck at explaining things but here's and answer :)
nine and two elevenths
9 2/11
101/11
as 11 is a prime number the fraction cannot be simplified further
Answer:
The total answer is $14.16 because the tip would be $2.16 so add it with 12 and you get $14.16.
Answer:
(1/8)(cos(4x) -4cos(2x) +3)
Step-by-step explanation:
Your answer is correct as far as it goes. You now need to use a power-reducing identity on the cos(2x)² term in your answer. The appropriate one is ...
cos(x)² = (1/2)(1 +cos(2x))
In the context of this problem, using this formula gives you ...
sin(x)⁴ = (1/4)(1 -2cos(2x) +(1/2)(1 +cos(4x))
sin(x)⁴ = (1/8)(cos(4x) -4cos(2x) +3)
