We have to find the quotient :
( 4 x³ y + 12 x² y³ - 20 x y ) / ( 4 x y ) =
= 4 x y ( x² + 3 x y² - 5 ) / ( 4 x y ) = ( Then 4 x y will be cancelled )
= x² + 3 x y² - 5
Answer:
D ) x² + 3 x y² - 5
Answer:
it is b.5/36
Step-by-step explanation:
Answer: D
Step-by-step explanation:
We are given X = 15 - 4y so simply replace any and all X's in the first equation with (15 - 4y). Option D is the best because the X is removed and replaced with the proper writing.

<u>Question</u><u>:</u></h2>
<u>find the height of the cylinder whose volume is 1.54 cubic m and radius of the base is 70 cm</u>
Required diagram :

<h3>Solution :</h3>
For a cylinder having a radius r and a height h ;
Volume Of Cylinder :
Here , the radius of the cylinder is given as 70 cm and the volume is 1.54 m³ .
Converting ;
- 1 m³ = 1 × 10⁶ cm³ .
- > 1.54 × 10⁶ cm³ .
- > 1540000 cm ³.
- > π r² h = 1540000
- > 22/7 × 70 × 70 × h = 1540000
- > 22 × 10 × 70 h = 1540000
- > 15400 h = 1540000
- > h = 100 cm = 1 m.
<u>The</u><u> </u><u>height</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>cylinder</u><u> </u><u>is</u><u> </u><u>100cm</u><u>.</u><u>=</u><u>1m</u><u>.</u>
Answer:
4x-2
Step-by-step explanation:
<u>First, distribute the minus sign.</u>
-2x+3-(5-6x)
-2x+3+ -1(5)+ -1(-6x)
-2x+3+ <em>(-5) </em>+ <em>(6x)</em>
-2x+3-5+6x
<u>Next, combine like terms.</u>
<em>-2x</em>+3-5<em>+6x</em>
(-2x+6x)+(3-5)
4x+(-2)
4x-2
