Answer:
x=7
Step-by-step explanation:
W(x)=3x-7
w(x)=14
3x-7=14
isolate x
3x=21
x=7
<u>ANSWER</u>
Extraneous solution: x=6
Real solution: x=11
<u>EXPLANATION</u>
The given expression is
Add -8 to both sides:
Square both sides.
We expand the to get
Write in standard quadratic form.
Factor to get:
We check for extraneous solutions by substituting each value of x into the original equation.
When x=6
Hence x=6 is an extraneous solution.
When x=11
This statement is true.
Hence x=11 is the only solution.
Answer:
9π/4 - 4.5 unit^2.
Step-by-step explanation:
The are of the segment = area of the sector - area of the triangle.
Area of the sector = 1/4 * area of the circle
= 1/4 π 3^2
= 9π/4. unit^2
Area of the triangle
= 1/2 * 3 * 3
= 9/2 unit^2.
So the answer is 9π/4 - 4.5 unit^2.
