Answer:
= (a + <u>4</u>) (a - <u>4</u>)
Step-by-step explanation:
The given equation is
Now, By ALGEBRAIC IDENTITY:
Here, taking , we get b = 4
as
So, the right hand side of is (a + 4) (a-4)
Raise b to the 8th power

For this case we have:
Note:<em> Milliliter is a unit of volume. It is not possible to convert distance units into volume units. </em>
We must convert the length 0.13 meters to millimeters.
By definition, 1 meter equals 1000 millimeters. That is to say:
Then, applying the rule of three we have:
1m ------------> 1000mm
0.13m --------> x
Where x represents the length of the marker in millimeters.
Resolving:
Thus, the marker measures 130 millimeters long
Answer:
130 millimeters
Answer:
9
Step-by-step explanation:
A quadratic equation is
The axis of symmetry is 1. This means that some value of
-b/2a =1.
f(0) represent one of the horinzontal roots. Since f(0) equal 0, the constant is 0.
Notice how x=1 is the line of symmetry. This means when x=4 and x=-2, the quadratic is equal. so consider this equation.
=-24
16a+4b= -24
4a-2b=-24
Solve for a by elimination.
2(4a-2b=-24)= 8a-4b=-48
Add both equations.
(16a+4b=-24)+(8a-4b=-48)= 24a=-92
Solve for a.
24a=-92
a=-3
Subsitute to in for b.
16(-3)+4b=-24
-48+4b=-24
4b=24
b=6
This means a=-3
b=6
So b-a is
6+3=9
