Answer:
Options A and B
i.e., A. 4(3) and B.
Step-by-step explanation:
Like radicals are similar to like terms.
For example,
x, 2x, -10x, , 7.3x are like terms.
are some more examples of like terms.
Similarly, like radicals are:
etc.

Answer:
(b) (x – 4)^2 + (y – 6)^2 = 16
Step-by-step explanation:
The equation for a circle with center (h, k) and radius r is ...
(x -h)^2 +(y -k)^2 = r^2
You want the equation for a circle with center (4, 6) and radius 4. That equation is ...
(x -4)^2 +(y -6)^2 = 16
Let x = the unknown number
five more than a number = twice the number
x + 5 = 2x
5 = 2x - x
5 = x
( Balance method is used to solve )
substitution
x + 5 = 2x
5 + 5 = 2 x 5
10 = 10
answer : the unknown number is 5
