Let x be the number of hours ling work on monday.
We know that she worked three more hours on tuesday that in monday, this can be express as :

We also know that in wednesday she worked on more hour than twice the number on mondays, this can be expressed as:

The total number of hours she worked this three days in two more than five the number of hours she worked on monday, this can be express as :

Now , once we have all the expressions we add the expressions of the days and equate them to the total

Now we solve the equation

Therefore , she worked 2 hours on monday.

Answer:
<h2>

</h2>
Step-by-step explanation:
f(x) = 2x + 4
g(x) = 4x² + 1
In order to find (g ∘ f)(0) we must first find
(g ° f )(x)
To find (g ° f )(x) substitute f(x) into g(x) that's for every x in g(x) replace it with f(x)
That's
<h3>

</h3>
We have
<h3>

</h3>
Now to find (g ∘ f)(0) substitute the value of x that's 0 into (g ∘ f)(0)
We have
<h3>

</h3>
We have the final answer as
<h3>

Answer:
Option (D)
Step-by-step explanation:
In the picture attached,
An obtuse angle triangle ABC has been given.
By applying Sine rule in the triangle,

Since, m∠A + m∠B + m∠C = 180°
45° + 110° + m∠C = 180°
m∠C = 180°- 155° = 25°



b = 
b = 15.56
b ≈ 15.56

a = 
a = 11.712
a = 11.71
Therefore, Option (D) will be the answer.
