Answer: The 3rd equation is a true proportion
Brainliest please! <3
I'll start 18 and 22 for you, and you should then be able to do the rest on your own!
For 18, what we literally do is apply the distance formula for all the points and add them up. For B to C, we get the distance between them to be
sqrt((x1-x2)^2+(y1-y2)^2)=sqrt((0-4)^2+(3-(-1))^2)=sqrt((-4)^2+4^2)=sqrt(16+16)=sqrt(32). Repeat the process for C to E, E and F, and F to B then add the results up to get your answer!
For 22, since the area of a rectangle is length*width (we know given the right angles and that the opposite sides are equal in how long they are), we can multiply 2 perpendicular lines, for example, BC and CE to get sqrt(32)*sqrt(8)=16 as the area
Answer:
Step-by-step explanation:
Here you go mate
Step 1
-8 =-0.8k Equation
Step 2
-8 =-0.8k Simplify
-8=-0.8
Step 3
-0.8k/-0.8=-8/-0.8
answer
k=10
For this case we have the following data:
Polynomial function of grade 5
Given roots: -2, 2,
Having an imaginary root given by 
, the other root, in the same imaginary way, must be given by its complex conjugate, that is, 
.
In this way, the fourth root is given by:
Since the polynomial function is grade 5, it must have 5 roots. Thus, the fifth root must be given by a real number.
Thus, the roots of the polynomial function are given by: three real roots and two imaginary roots.
