Answer:
No he was not correct
Step-by-step explanation:
The Equation is 15 x + 6 = 14 x + 5
now By the steps brandon used let us solve the question
Step 1 : Add 14 negative x tile to both sides
which will make the equation
15x + 6 - 14x = 14x + 5 - 14 x
x + 6 = 5 .......(ii)
Step 2: Add 5 negative unit tiles to both sides of equation (ii)
which will make the equation
x +6 - 5 = 5 - 5
x + 1 = 0 .........(iii)
Step 3: x =1 is the answer
but from equation (iii) we see that
x + 1 =0
by adding -1 on both sides
x + 1 -1 = 0-1
x = -1
So the step three done by Brandon is wrong which explains he was not correct
Use the distance formula, AB=√[(1-(-9)]²+[(-1-(-3)]=√[100+4]=√104
use the same formula, AC=√52, BC=√52
AC²+BC²=52+52=104=AB²
Yes, it is a right triangle.

Sorry if I'm wrong
Answer:
The answer should be C. By combining like terms you can find the answer. 1.75a+2.75a = 4.5a
2.25b + 1.75b = 4b
2.25c + 1.25c = 3.5c
