I think you're supposed to add all the fives together. That is what MY teacher taught me to do :/
Step-by-step explanation:
The shape is a square that is tilted and looks like a rhombus. Just add the 5's together.
Answer:
Formulas for a rectangular prism:
Volume of Rectangular Prism: V = lwh.
Surface Area of Rectangular Prism: S = 2(lw + lh + wh)
Space Diagonal of Rectangular Prism: (similar to the distance between 2 points) d = √(l2 + w2 + h2)

Hope it helps :))))
Answer:
<h3>
Assuming A, B, and C are collinear and B is between A and C then BC = 35 </h3>
Step-by-step explanation:
Assuming A, B, and C are collinear and B is beetween A and C
AB + BC = AC
2x + 6 + 6x + 5 = 51
8x + 11 = 51
8x = 40
x = 5
BC = 6x+5 = 6×5 + 5 = 35
Answer:
Therefore the given vectors are orthogonal for b = 0,±3.
Step-by-step explanation:
If 
and 
are two vectors orthogonal, then the dot product of and will be zero.
i.e 
If 
and 
Given two vectors are (-18,b,9) and (b,b²,b)
Let
and
Therefore,
=(-18).b+b.b²+9.b
= -18b+b³+9b
= b³-9b
Since 
and 
are orthogonal. Then = 0.
Therefore,
b³-9b= 0
⇒b(b²-9)=0
⇒b =0 or b²=9
⇒b=0 or b =±3
Therefore the given vectors are orthogonal for b = 0,±3.
