»f(x) = 9(9 + x)(10)
subtitute x = 2 for f(x).
»f(5) = 9(9 + 5)(10)
»f(5) = 9(14)(10)
»f(5) = 1,260✅
The answer is 20 because you dive it
Answer:
The answers to the first question are A,C,D
The answer to the second question is YZ=16
Step-by-step explanation:
(1st Question)
Since <K and <M Are equal, and both <L's are equal, KL and ML are congruent (Answer choice) because of the ASA postulate.
You need to create the following equation to find the length of KN and MN 7x-4=5x+12
(Get the "x" variable to one side)
2x-4=12
(Isolate the variable)(Remove the 4)
2x=16
(Divide the 2 by itself to remove it from the x, remember to divide both sides by 2)
x=8 (Answer Choice)
Plug in the x value into each equation
KN= 7(8)-4
KN= 56-4
KN= 52
MN= 5(8)+12
MN= 40+12
MN= 52 (Answer Choice)
MN=KN
(Second Question)
Since XWY(20) is half of XWZ(40), ZWY also equals 20.
This now proves the triangle is congruent by the AAS postulate.
Since the triangles are congruent, if XY = 16, YZ also equals 16.
The volume of the cylindrical candle that has a base area of 12.56 inches is 12.56h inches³.
<h3>Volume of of cylinder</h3>
volume of a cylinder = πr²h
where
Therefore,
volume of a cylinder = πr²h
Area of the base = πr²
Therefore,
Area of the base = 12.56 inches²
volume of the cylindrical candle = 12.56h inches³
