Original length: x
original width; x-3
original area: x(x-3)
when the dimensions doubles, that is, increase by a factor of 2, the area increase by 2²
4[x(x-3)]
4x(x-3)=4x²-12x
you can also do it this way:
original length: x doubled: 2x
original width; x-3 doubled: 2(x-3)
new area: 2x[2(x-3)]= 4x²-12x
Answer:i would 1*/
Step-by-step explanation: because
5x - 2x + 8 = 2 + 6x + 6
Add like terms:
5x - 2x = 3x
2 + 6 = 8
3x + 8 = 6x + 8
To isolate the variable, subtract 6x from both sides of the equation:
3x - 6x = -3x
-3x + 8 = 8
Now subtract 8 from both sides:
8 - 8 = 0
-3x = 0
To finish, divide both sides by -3:
0 ÷ -3x = 0
The answer is x = 0

Answer:
x = 8
Step-by-step explanation:
If j(x) = -5
j(x) = 3 - x
-5 = 3 - x
x = 3 + 5
x = 8
