Combine any like terms in the expression. If there are no like terms, rewrite the expression. (NO TROLL ANSWERS, OR ELSE!)
Answer:
48+36r³
Step-by-step explanation:
There are two pairs of like terms in this expression: 19r³ and 17r³, 44 and 4
Combining the two pairs, you get 48+36r³
Could someone help me please?
Answer:
600
Step-by-step explanation:
So lets rememer the formula for volume of a pyramid to sovle this:
LxHxW/3
Now lets plug in our values, for L, H, and W.
15x12x10/3
So, 15x12x10 is 1800. That is the height times the length times the width.
Now, since this isnt volume of a cube, we must divide the total my 3. This is how you find the volume of a pyramid, as I said above.
So it should be:
1800/3
=
600
This is your answer.
I hope this helps : )
Good luck!
What is the value of the contangent of
Given:
In triangle WXY, [tex]m\angle W=90^\circ, WX=8, XY=17, WY=15[/tex].
To find:
The Cotangent of [tex]\angle X[/tex].
Solution:
In a right angle triangle,
[tex]\cot \theta=\dfrac{Base}{Perpendicular}[/tex]
It can be written as:
[tex]\cot \theta=\dfrac{Adjacent}{Opposite}[/tex]
For triangle WXY,
[tex]\cot (\angle X)=\dfrac{WX}{WY}[/tex]
[tex]\cot (\angle X)=\dfrac{8}{15}[/tex]
Therefore, the Cotangent of [tex]\angle X[/tex] is [tex]\dfrac{8}{15}[/tex].
