Answer:
6x3+11-3=26
Step-by-step explanation:
Which is the side length of a cube with a volume of 64 m3?
<em>Volume: 64m</em>³
a^3 = 64
<span>\sqrt[3]{64}</span> [/tex] = 4 m

the answer
Check
4 * 4 * 4 = 64 m³
By "y = −9x2 − 2x" I assume you meant <span>y = −9x^2 − 2x (the "^" symbol represents exponentiation).
Let's find the first derivative of y with respect to x: dy/dx = -18x - 2. This is equivalent to the slope of the tangent line to the (parabolic) curve. Now let this derivative (slope) = 0 and solve for the critical value: -18x - 2 = 0, or
-18x = 2. Solving for x, x = -2/18, or x = -1/9.
When x = -1/9, y = -9(-1/9)^2 - 2(-1/9). This simplifies to y = -9/9 + 2/9, or
y = -7/9.
The only point at which the tangent to the curve is horiz. is (-1/9,-7/9).</span>
c is the answer because negative numbers have to go first
X²+20-20=4-20
x²=-16
Take the square roots of each side: x=the square root of -16
You cannot do this so there is no solution
However, I'm not perfectly sure, so wait for other answers just in case
