Answer:
-1 8/9
Step-by-step explanation:
w + ( - x)
w = -5/9
z = 4/3
Input:
-5/9 + ( -4/3)
-5/9 - 4/3
-4/3 * 3/3 = -12/9
-5/9 - 12/9 = -17/9 = -1 8/9

Step-by-step explanation:
Add 9 to both sides of the equation.
if you want to create a trinomial square on the left, find value that is equal to the square of half of b
Add the term to each side of the equation
SIMPLIFY >:(
How to Simplify it:
-Raise the -2 to the power of 2
and ten simplify 9 + (-2)^2 :
--Raise -2 to the power of 2 and then add 9 and 4
Factor the perfect trinomial square into (x - 2)^2
Solve the equation for x
How to do it:
-Take the square root of each side of the equation to set up the solution for x
--Then remove the perfect root factor, x - 2 under the radical to solve for x
---Remove parenthesis
----add 2 to both sides of the equation.
the final answer could be shown in different ways,but the exact form is x=±√13+2
In decimal form its x=5.60555127…,−1.60555127…
--this took me like 7 minutes to do im no geek tho lol
The measure of the central angle is 4 radians
<h3><u>
Solution:</u></h3>
Given that central angle of a circle intercepts an arc of length 28 centimeters
The radius of the circle is 7 centimeters
<em><u>To find: measure of the central angle in radians</u></em>
The arc length of circle when
is measured in radians is given as:

Where "s" is the arc length
"r" is the radius of circle
is the central angle in radians
Substituting the values in formula,

Thus the measure of the central angle is 4 radians
