What is the cosine law?
The squared of the size of any solitary side of either a triangle is equal, by the cosine rule, to the total of the squares of the lengths of the other two sides, times by the cosine of something like the angle they are a part of.
Let the triangle ΔABC, then the cosine law is given as,
c² = a² + b² - 2 a·b cos C
In ΔABC, if the length of sides a, b, and c are 3.5 centimeters, 5.5 centimeters, and 6 centimeters respectively. Then the measure of the angle ∠C is given as,
6² = (3.5)² + (3.5)² - 2 · (3.5) · (3.5) cos C
Simplify the equation, then we have
6² = (3.5)² + (3.5)² - 2 · (3.5) · (3.5) cos C
36 = 12.25 + 12.25 - 24.50 cos C
11.5 = - 24.50 cos C
cos C = - 11.5 / 24.5
C = 117.99
The measure of the angle ∠C to two decimal places will be 117.99°.

The value will be 4a.
Expression
In mathematics, an expression is defined as a set of numbers and mathematical operations that is formed according to rules which is dependent on the context.
Given to us,
equation 1,
equation 2,
Let's assume t=4a,
substituting the value of t in equation1, we get
As we can see we get equation 2 again, therefore, the value will be 4a.

Answer:
Step-by-step explanation:
Given the function is ........... (1)
Now, we are given that .......... (2)
Now, the left hand side of both the above equations (1) and (2) are similar and the only change is that t is replaced by 4a.
Therefore, the equation (2) can be written as
(Answer)
Since we know that if then

in form ax²+bx+c=0
when b²-4ac>0, it has 2 real roots
when b²-4ac=0, it has 1 real root
when b²-4ac<0, it has no real roots
so
we solve for no real roots
b²-4ac<0
a=3
c=7
b=-m
(-m)²-(4)(3)(7)<0
m²-84<0
add 84 both sides
m²<84
sqrt both sides
m<9.1 about
nearest integer
round down
m=9
answer is m=9
