Answer:
C
Explanation:
If they repeat the experiment themselves, then they'll see if his conclusion is correct or not.
A mathematical pair that is <u>equivalent</u> to the given expression
is -20 + 48i.
<u>Given the following expression:</u>
To determine a mathematical pair that is equivalent to the given expression:
In this exercise, you're required to solve for a mathematical expression that is equivalent to the given expression. Thus, we would simplify the expression by applying the perfect-square trinomial.
<h3>The perfect square trinomial.</h3>
Mathematically, the perfect-square trinomial is given by this expression:
![(a+b)^2=a^2+2ab +b^2](https://tex.z-dn.net/?f=%28a%2Bb%29%5E2%3Da%5E2%2B2ab%20%2Bb%5E2)
Comparing the expressions, we have:
Substituting the values, we have:
![(4+6i)^2=4^2+2(4)(6i) +(6i)^2\\\\(4+6i)^2=16+48i +36i^2](https://tex.z-dn.net/?f=%284%2B6i%29%5E2%3D4%5E2%2B2%284%29%286i%29%20%2B%286i%29%5E2%5C%5C%5C%5C%284%2B6i%29%5E2%3D16%2B48i%20%2B36i%5E2)
<u>Note:</u>
= -1
Simplifying further, we have:
![(4+6i)^2=16+48i +36(-1)\\\\(4+6i)^2=16+48i -36\\\\(4+6i)^2=-20+48i](https://tex.z-dn.net/?f=%284%2B6i%29%5E2%3D16%2B48i%20%2B36%28-1%29%5C%5C%5C%5C%284%2B6i%29%5E2%3D16%2B48i%20-36%5C%5C%5C%5C%284%2B6i%29%5E2%3D-20%2B48i)

Answer:
I put 7 but im not sure if it correct yet
Explanation:
if point U is on RS but the U to P is 7 units then U must be the midpoint of RS but i have no idea hope this helps
Decreased crops, decreased wildlife, I don’t know the rest though
Good Luck
Answer:
Qualified.
Explanation:
I'm assuming this is the answer because I have seen one exactly the same on Edgenuity 2020.
