4√30^2 times 3√20x

(i will mark you brainliest if you answer this correctly)

720

Step-by-step explanation:

First you want to simplify both of them. To do this on 4 you can just cancel out the square and the square root to get 4 x 30 which is 120. Now you simplify 3 you do this by splitting the radical into 2 radicals. So you want to take out a perfect square which in this case is and you have left over. This brings us to 120 x 3 x 2 (2 is the square root of 4) . Now multiply 120 x 3 x 2 and get 720.

each side has a different length.  

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
