To find the zero you must set each factor equal to zero and solve for for x like so...
Factor (x - 7)
x - 7 = 0
x = 7
Factor (x + 4)
x + 4 = 0
x = -4
Factor (3x - 2)
3x - 2 = 0
3x = 2
x =
All the zeros are:
-4,
, 7
Hope this helped!

All the interior angles of a triangle always add up to 180 degrees.
3x + (2x + 20) + (4x - 20) = 180
3x + 2x + 20 + 4x - 20 = 180
3x + 2x + 4x + 20 - 20 = 180
10x = 180
x = 180/10
Therefore, x = 18
Answer:

Step-by-step explanation:
<u><em>The correct question is</em></u>
what is the equation for a line passing through (-2,3) and perpendicular to y= -1/2<em>x</em>+1 ?
Remember
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes are equal to -1)
The slope of the given line is m=-1/2
so
the opposite reciprocal is m=2
<em>Find the equation of the line in point slope form</em>

we have

substitute

<em>Convert to slope intercept form</em>

isolate the variable y



Answer:
5
Step-by-step explanation:
(2x + y) - z
Let x=3 y=4 and z=5
2*3 +4 -5
Multiply and divide first
6 +4 -5
Then add and subtract
10-5
