The answer to this would be D
Answer:
It does not matter whether you multiply the radicands or simplify each radical first. You multiply radical expressions that contain variables in the same manner. As long as the roots of the radical expressions are the same, you can use the Product Raised to a Power Rule to multiply and simplify.
Step-by-step explanation:
X-5 + 5x-12 = 25
combine like terms
6x-17 = 25
add 17
25 + 17 =42
6x + 42
x = 7
I'm not sure what you mean by "the 3 consecutive numbers of 72".
Do you mean 3 consecutive numbers that ADD UP TO 72 ?
If that's what you want, then you can use this equation:
The middle number . . . . . x
The smallest number . . . . (x-1)
The biggest number . . . . . (x+1)
The equation: (x-1) + (x) + (x+1) = 72 .
Boil that equation down, and you discover that x=24 .
So the 3 numbers are 23, 24, and 25 .

Answer:
<h2>The answer is option D</h2>
Step-by-step explanation:
To find the equation of a line given the slope and a point we use the formula
<h3>
</h3>
where
m is the slope
( x1 , y1) is the point
From the question
slope = 0
The point is (- 2 , 7)
Substitute the values into the above formula and solve
That's
<h3>
</h3>
We have the final answer as
<h2>
</h2>
