Answer:
C
Step-by-step explanation:
C: AB is the radius of both circles.
Lateral area is the total surface area. A cube has 6 faces.
Lateral area = 6x²
<span>6x² = 144
</span>
<span>x² = 144/6
</span>
<span>x² = 24
</span>
<span>x² = </span>√24
x ≈ 4.899 km
Answer:
B. -4<x<2
Step-by-step explanation:
The highest x point is -4 and lowest peak is 2
Answer:
3x(2x^2 +x-1)
Step-by-step explanation:
f(x) = 11x^3 + 3x^2 - 4x + 2,
g(x) = 5x^3 - 7x + 2,
f(x) - g(x) =11x^3+3x^2-4x+2 - (5x^3-7x + 2)=
11x^3+3x^2 -4x+2-5x^3+7x-2=
(11x^3-5x^3)+3x^2+(-4x+7x)+(2-2)=
6x^3 +3x^2 - 3x=
3x(2x^2 +x-1)
