Answer:

12x^2+ 4y^2-26xy

Step-by-step explanation:

2x times 6x= 12x^2

2x times -y=-2xy

-4y times 6x= -24xy

-4y times -y= 4y^2

12x^2- 2xy- 24xy +4y^2

12x^2+ 4y^2-26xy

I hope this is right, sorry if its not

Answer:

12x^2-26xy-4y^2

Step-by-step explanation:

You can use f.o.i.l, or the box method.

I have drawn a picture for you to show the box method if you didn't know so. To add on to the picture, you need to combine these terms, and if there any like terms you combine them to get the simplified version.

12x^{2}-24xy-2xy-4y^{2}

You can combine -24xy and -2xy which will give you -26xy

So your final answer will be

12x^2-26xy-4y^2

Please help me with these, find the missing side. Thank yu only if you know
abruzzese [7]

Answer:

7.48m (3s.f.)

Step-by-step explanation:

Let the missing side be x m.

Applying Pythagoras' Theorem,

x² +5²= 9²

x² +25= 81

x²= 81 -25 <em>(</em><em>-25</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

x²= 56

x =  \sqrt{56}

x = 2 \sqrt{14}

x= 7.48 (3 s.f.)

∴ The missing side is 7.48 m (3s.f.)

What is the volume of a square pyramid with base edges 24 feet and slant height 37
-Dominant- [34]

Answer: The volume of pyramid is 6720 ft³

Step-by-step explanation:

Given: Base edge of a square pyramid = 24 feet

Slant height = 37 feet

Therefore height of pyramid is given by

h^2=l^2-\dfrac{1}{2} b^2 where h is height, l is slant height and b is base edge of pyramid

So we have

h^2= 37^2-(\dfrac{1}{2} \times 24)^2= 37^2-12^2=1225 \\\\\Rightarrow h= \sqrt{1225} =35

Height of pyramid is 35 feet

Now the volume of a pyramid is given by

V=b^2\dfrac{h}{3} where V is volume , b is base edge and h is height of pyramid

Therefore

V= (24)^2\dfrac{35}{3} = 6720

Hence , the volume of pyramid is 6720 ft³
