Answer:
cos3x+tan3x=0
⟹cos3x=−tan3x
⟹cos3x=−sin3xcos3x
⟹cos23x=−sin3x
⟹1−sin23x=−sin3x
⟹sin23x−sin3x−1=0
This is a quadratic equation in sin3x.
sin3x=−(−1)±(−1)2−4×1×(−1)−−−−−−−−−−−−−−−−−√2×1
sin3x=1±5–√2
If x takes real values, the upper sign must be rejected.
sin3x=1−5–√2
⟹3x=nπ+(−1)nsin−11−5–√2
⟹x=13[nπ+(−1)nsin−11−5–√2]

Answer:
a. ben eats 27 apples
b. ben has 18 apples left
The solution for the expression (v²)(m⁴)/(v²)(m³) will be m. The correct option is C.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The given expression will be solved as below:-
E = (v²)(m⁴)/(v²)(m³)
Divide v² by the same term v².
E = (m⁴)/(m³)
E = m
Therefore, the solution for the expression (v²)(m⁴)/(v²)(m³) will be m. The correct option is C.

+ 6 +
= 18
First, simplify
to
/ Your problem should look like:
+ 6 +
= 18
Second, simplify
to
/ Your problem should look like:
+ 6 +
= 18
Third, simplify
+ 6 +
to
+ 6 / Your problem should look like:
+ 6 = 18
Fourth, regroup terms. / Your problem should look like: 6 -
= 18
Fifth, multiply both sides by 7. / Your problem should look like: 42 - x = 126
Sixth, subtract 42 from both sides. / Your problem should look like: -x = 126 - 42
Seventh, simplify 126 - 42 to 84. / Your problem should look like: -x = 84
Eighth, multiply both sides by -1. / Your problem should look like: x = -84
Answer:
x = -84
