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.

11 ft 8 in
2 ft 9 in
-----------------add
13 ft 17 in
1 ft = 12 in.....so 17 in = 1 ft 5 in
13 ft + 1 ft 5 in = 14 ft 5 in <=== 14 ft and 5 inches
Answer:
Y = 4x +2
Step-by-step explanation:
Y = mx + b where m = slope and b = y-intercept
Answer:
I think you are correct but I'm not sure
Step-by-step explanation:
Answer:
When x=2
Step-by-step explanation:
Well in the first one it tells you that 2x is 90.
In the second it's y=40x+10
So you plug 2 in as the x.
y=40(2)+10
y=80+10
y=90
Hope this helps
