Answer:
Total area = 26.13 ft²
Step-by-step explanation:
area of a triangle = 1/2 x base x height
From inspection, the base of the triangle = 3 x 2 = 6
and the height of the triangle = 4
⇒ area = 1/2 x 6 x 4 = 12 ft²
area of a semicircle =
⇒ area =
⇒ area = 14.13 ft²
Total area = 12 + 14.13 = 26.13 ft²
Answer:
There is one extraneous solution at
The only solution is
Step-by-step explanation:
Given:
The equation to solve is given as:
In order to solve, we will first isolate the radical part.
<em>Adding -5 on both the sides, we get:</em>
<em>Now, squaring both the sides, we get:</em>
Now, let us check whether the calculated values satisfy the equations or not.
Plug in 4 and 7 for 'x' and check the value of the equation.
At ,
But, 6 is not equal to 4 and hence 4 is not a solution to the given equation. It is an extraneous solution for the given equation.
Now, at
Therefore, is a solution to the equation.
Hence, there is one extraneous solution at
The only solution is
