Please help ASAP!! Rah write a polynomial expression in standard form using one variable, a, that has 4 terms and is degree 5

Nicole write a polynomial expression in standard form using one variable, a, that has 3 terms and is degree 2.

Raj and Nicolasa polynomial expressions are added to create a sum, written in standard form.

What can you determine about the degree of the sum?
The sum will be degree...?

What can you determine about the number of terms of the sum?
The maximum number of terms of the sum is, but could be less.

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12
