Answer:
The model represents the equation
-3x + 6 = 4x -8
Start by subtracting 6 from both sides.
-3x + 6 (-6) = 4x - 8 (-6)
-3x = 4x - 14
Subtract 4x from both sides
-3x - 4x = 4x - 4x - 14
-7x = -14
x = -14/-7
x = 2
Answer:
c
Step-by-step explanation:
252 = 7 *36
36 = 6 *6 = 6²
a² -b² = (a + b)(a - b)
7h² - 252k² = 7(h² - 36k²)
= 7(h² - [6k]² )
= 7(h +6k)(h - 6k)
Hey, there! For this question, we can just start by plugging in the known values.
can be rewritten as
.
Combine like terms: 
If you add x to
, x will become
, which means that x/2 + x = 3/2x.
--> 
If you rearrange this, then your answer will be option b. Hope this helps.
Y-1=4(x-(-2))
y-1=4x+8
Is this what you wanted ?
Answer:
width = 12 yards
Step-by-step explanation:
width: x
length: x + 3
perimeter: 54
x + x + (x + 3) + (x + 3) = 54
4x + 6 = 54
subtract 6 from both sides
4x = 48
x = 12
width: 12
length: 12 + 3 = 15
