Answer:
7*x + y + 0.1*z
Step-by-step explanation:
An expression that satisfy what Ava said she wrote is the following:
7*x + y + 0.1*z
because
- it has 3 terms (each summand);
- the coefficient (the number that multiplies the variable) of the first term is 7, of the second term is 1 (it is omitted because 1*y = y) and of the third term is 0.1;
- each term involves a different variable: x, y and z.

Answer: orthogonal </h3>
===========================================================
Explanation:
For any two vectors defined as follows
u = <a,b>
v = <c,d>
the dot product is computed by
u dot v = a*c + b*d
If the dot product of the vectors is 0, then the vectors are orthogonal. Meaning they are perpendicular to one another.
-------------------
Let's find the dot product of these two given vectors
u = < 2, -4 >
v = < 6, 3 >
u dot v = 2*6 + (-4)*3
u dot v = 12 - 12
u dot v = 0
Therefore, these two vectors form a right angle and are <u>orthogonal</u>
-------------------
Extra info:
If we can show that u = <a, b> and v = <ka, kb> for some real number k, then we have shown that vectors u and v are parallel.
Answer:
width = 5k^2
length( 3k^2 +7k +4)
Step-by-step explanation:
15k^4 +35k^3 +20k^2
The width is the greatest common factor
We can factor 5k^2 out
5k^2( 3k^2 +7k +4)
The length is what is inside the parentheses
