I need the solution and the work for it... for each of the multiple choices.
Vlad1618 [11]

For this case we have the following equation:

x ^ 3 = 375

We must find the value of "x":

We apply cube root on both sides of the equation to eliminate the exponent:

x = \sqrt [3] {375}

We can write 375 as 5 ^ 3 * 3

So:

x = \sqrt [3] {5 ^ 3 * 3}\\x = 5 \sqrt [3] {3}

Then, the correct options are:

x = \sqrt [3] {375}\\x = 5 \sqrt [3] {3}

Answer:

Option A and B

first multiply ac
4 times 5=20
now
what 2 numbers multiply to 20 and add to 12
2 and 10
4x²+2x+10x+5
group
(4x²+2x)+(10x+5)
undistribute
2x(2x+1)+5(2x+1)
