Answer
The answer is C. Trina is not correct because the two sides of the equation are equivalent.
Step-by-step explanation:
1. solve for x
-8(x - 4) + 2x = -4(x - 8) -2x
-8x + 32 + 2x = -4x + 32 -2x
-6x + 32 = - 6x + 32
0 = 0
This equation has infinite solutions, any rational number fits as solution for x in this equation. And as we can see both sides of it are equivalent.
Therefore, the correct answer is C. Trina is not correct because the two sides of the equation are equivalent.

Divide 72 by 9 and multiply that outcome (8) by 5 points
72/9=8
8(5)=40
Answer:
(5)
Step-by-step explanation:
The given two points are:
A(3,k) and B(h,4)
Now, using the distance formula that is=.
In the given points, ,, and , thus,
=
which is the required equation, hence option 5 is correct.
Answer:
19.71 m
Step-by-step explanation:
we have to set up a equation
If you draw a picture to set up the similar parts, it will help you to make a proportion for the equation easier.
using right angle triangle theory
bases = represent the shadows
heights = heights of the tree and the statue
height of tree/height of statue = shadow length of tree /shadow length of statue
Height of tree= shadow length of tree x height of statue /shadow length of statue
Height of tree= 26 x 47/ 71 = 19.71 m
