Answer:
C) 3x - 6
Step-by-step explanation:
Let the unknown number be represented by placeholder x.
Then the product of 3 and the number is represented by 3*x or 3x.
This value diminished by 6 corresponds to 3x-6.
So the expression representing the required overall construct mathematically is given by 3x-6
Option a, 6x-3 represents the difference of 6 times x and 3.
Option b, 3-6x represents the difference of 3 and (6 times x).
Option d, 6-3x represents the difference of 6 and (3 times x).

Answer:
A = -9, B = 65
Step-by-step explanation:
Take the square root of both sides of the equation:
h + 9 = ±√65
Subtract 9 from both sides of the equation:
h = -9 ± √65
Comparing this to the form
h = A ± √B
we see that A = -9 and B = 65.

A lot of math is about matching patterns of numbers and variables. Here, you're asked to match the expression -9±√65 to the pattern A±√B and identify the values for A and B that make these expressions identical.
It should not be difficult to see that the stuff on the left side of ± is the value of A. That stuff is -9.
The stuff under the radical is the value of B. That stuff is 65.
