san4es73 [151]

Answer:

Options A and B

i.e., A. 4(3\sqrt{7x}) and B. \sqrt{7x}

Step-by-step explanation:

Like radicals are similar to like terms.

For example,

x, 2x, -10x, \frac{1}{2} x, 7.3x are like terms.

taurus [48]

Answer:

A). X = -3

Step-by-step explanation:

Step 1: Add 20 to both sides.

  • 7x-20+20=-41+20
  • 7x=-21

Step 2: Divide both sides by 7.

  • 7x/7 = -21/7\\
  • x=-3

Step 3: Check if solution is correct.

  • 7(-3)-20=-41
  • -21-20=-41
  • -41=-41
