➷ You can form this equation:
(call the unknown number x)
8x - 66 = 2x
Add 66 to both sides:
8x = 2x + 66
Subtract 2x from both sides:
6x = 66
Divide both sides by 6:
x = 11 <== this is the number

The last one CL because of the order
Answer:
P = 6x³ + 12x² - 18x + 8
Step-by-step explanation:
Given that:
Length = 3x3+4x2−6x
Width = 2x2−3x+4
The length of fencing needed will be :
Perimeter of rectangle (P) = 2( Length + Width)
P = 2[ (3x3+4x2−6x) + (2x2−3x+4)]
P = 2 (3x³+ (4x² + 2x²) + (-6x - 3x) + 4)
P = 2(3x³ + 6x² - 9x + 4)
P = 6x³ + 12x² - 18x + 8
