The radicand is what part of the radical

Step-by-step explanation: The expression shown in the image provided can be read as "the square root of 25."

The symbol that we use for square rooting a number is called the radical and the number inside the radical which in this case is 25 is called the radicand.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

the answer is 21%.
