Answer:
Total number of trees planted = 
trees
Step-by-step explanation:
Trees planted by each student = 
Total number of students = 
Using unitary method to find total number of trees planted by all the students in school.
1 student plants = trees
student would plant = 
We apply the product rule of exponents to multiply ![[a^xa^y=a^{x+y}]](https://tex.z-dn.net/?f=%5Ba%5Exa%5Ey%3Da%5E%7Bx%2By%7D%5D)
⇒ 
⇒ 
⇒ trees
Total number of trees planted = trees

<h3>Answer:</h3>
Yes, ΔPʹQʹRʹ is a reflection of ΔPQR over the x-axis
<h3>Explanation:</h3>
The problem statement tells you the transformation is ...
... (x, y) → (x, -y)
Consider the two points (0, 1) and (0, -1). These points are chosen for your consideration because their y-coordinates have opposite signs—just like the points of the transformation above. They are equidistant from the x-axis, one above, and one below. Each is a <em>reflection</em> of the other across the x-axis.
Along with translation and rotation, <em>reflection</em> is a transformation that <em>does not change any distance or angle measures</em>. (That is why these transformations are all called "rigid" transformations: the size and shape of the transformed object do not change.)
An object that has the same length and angle measures before and after transformation <em>is congruent</em> to its transformed self.
So, ... ∆P'Q'R' is a reflection of ∆PQR over the x-axis, and is congruent to ∆PQR.
