Answer:

A'(4,-5), B'(1,-6), C'(2,-3)

Step-by-step explanation:

Reflect across the line y = -1 to get these points. You can count how many points it takes to get to that line and then add the same amount of points to the other side.

216 raised to the power 1/3 can also be written as cube root of 216. 

Changing the given expression to radical form, we can write:

(216)^{ \frac{1}{3} }  \\  \\ 
= \sqrt[3]{216}

216 is the cube of 6 i.e. multiply 6 three times (6 x 6 x 6), you will get 216.
So we can write the above expression as:

\sqrt[3]{(6)^{3} }

The cube root and cube cancel out each other, leaving the answer equal to 6.

So, the correct answer is option B

Can someone help me with this? My teacher said its a must in the homework and i cant find a solution.
andrezito [222]

Answer:

8x^3+28x^2-16x

Step-by-step explanation:

Volume of rectangular prism: l*b*h (l = length, b = breadth, h = height.)

Volume of rectangular prism:

(x+4)*(2x-1)*4x

4x\left(x+4\right)\left(2x-1\right)

Expand the two brackets using FOIL:

4x(x* \:2x+x\left(-1\right)+4* \:2x+4\left(-1\right))

4x\left(2x^2+7x-4\right)

Expand:

4x* \:2x^2+4x* \:7x+4x\left(-4\right)

8x^3+28x^2-16x
