Answer:
x = 12
Step-by-step explanation:
sqrt(x+4) - 3 = 1
First get the sqrt all by itself on one side of the equation. Add 3 to both sides of the equation.
sqrt(x+4) = 1 + 3
sqrt(x+4) = 4
To "fix" the sqrt, that is, "undo it" and get rid of it, you have to SQUARE both sides of the equation.
(sqrt(x+4))^2 = 4^2
x + 4 = 16
subtract 4 to finish up.
x = 12
Check:
sqrt(12 + 4) - 3 = 1
sqrt16 - 3 = 1
4 - 3 = 1
1 = 1 Check!
A plane cuts horizontally across a rectangular pyramid will always be a rectangle. (Answer B)
Answer: No
Explanation: The relation is not a function because there is more than one output (y) for a single input (x).
Answer:
From this, you can tell it's in slope-intercept form, has a slope of -1/2, and a y-intercept of -4.
I've included a picture of what this equation looks like.
Answer:
The answer is
<h2>4m ( m + 3x) ( m - 2)</h2>
Step-by-step explanation:
4m³ + 12xm² - 8m² - 24xm
Factorize the GCF out
The GCF of 4 , 12 , 8 and 24 is 4
So we have
4( m³ + 3xm² - 2m² - 6xm)
Next factor m out
We have
4m( m² + 3xm - 2m - 6x)
Factorize the terms in the bracket
That's
4m[ m( m + 3x) - 2 ( m + 3x) ]
Next factor ( m + 3x) out
We have the final answer as
<h3>4m ( m + 3x) ( m - 2)</h3>
Hope this helps you
