The correct option is D:
the curves do not intersect, so there is no solution
<h3>
For what values of x are the two areas equal?</h3>
The area of the rectangle is given by:
f(x) = (x + 7)*(5x - 3)
f(x) = 5x² -3x + 35x - 21
f(x) = 5x² + 32x - 21
For the circle, the area is:
g(x) = 2*pi*(x + 6)^2
g(x) = 2pi*x^2 + 12pi*x + 72pi
The solution is given g(x) = f(x).
By graphing both functions (the green curve is the area of the rectangle, the orange one is the area of the circle). The two curves never do intercept, so the correct option is D.

Answer:
x<3
Step-by-step explanation:
-9.5x-1.5>-30
move the constant to the right
-9.5x>-28.5
divide both sides to get x<3
Add both sides by 16
so you'll have x^4 =16
take the 4th root of both sides and you'll get x= 2
Answer:
Well, I am not sure which one is equivalent to another, but I have some information that should help you find your answer.
Step-by-step explanation:
The simplified expression to x2 − x − 6 x2 + 2x − 15 would be equal to −5 x 2 + x − 15.
The simplified expression to x + 3 x + 5 would be equal to 4x + 5.
The simplified expression to x + 2x + 5 would be equal to 3x + 5.
The simplified expression x + 3 x − 3 would be equal to 4x − 3.
The last simplified expression to x + 2 x − 3 would be equal to 3x − 3.
Hope this helps, I am really sorry if I didn't answer your question properly, or the way you asked!
Answer:
5
Step-by-step explanation:
-x = 4 - 3x + 6
3x-x = 4 + 6
2x = 10
x = 5
