(5r - 4)(r² - 6r + 4)
distributive property of multiplication.
5r(r² - 6r + 4) - 4(r² - 6r + 4)
5r³ - 30r² + 20r - 4r² + 24r - 16
group like terms and simplify.
5r³ - 30r² - 4r² + 20r + 24r - 16
5r³ - 34r² + 44r - 16 Choice A.
Hey,here is the answer to ur question......!!!!
Since it is a square and all angles =90
Therefore to
Find length of the diagonal we have to use Pythagoras theorem....!
So, (AC)^2=(AB)^2+(BC)^2
=>(AC)^2=(11)^2+(11)^2
=>(AC)^2=121+121
=>(AC)^2=242
=>AC=root242
=>AC=11root2
=>length of the diagonal =11root2
Hope this helps u....!!!!
The question is missing the figure. So, it is attached below.
Answer:
Area of the shaded sector is <u>144π units squared</u>.
Step-by-step explanation:
Given:
Central angle of the sector is, 
Radius of the circle is, 
We know that, area of a sector of a circle of radius 'R' and central angle
is given as:

Plug in
. This gives,

Therefore, the area of the shaded sector is 144π units squared.
