You would need to add 5 to the opposite side so the balance scale stays 17.
Considering the formulas for the area and the perimeter of the rectangle, the one with the desired measures is given as follows:
a length of 3 units and a width of 4 units.
<h3>What are the area and the perimeter of a rectangle?</h3>
Considering a rectangle of length l and width w, we have that:
For a rectangle with a length of 3 units and a width of 4 units, we have that:
- A = 3 x 4 = 12 square units.
Hence it is the correct option.

Answer:
(x-1)(x-9)
Step-by-step explanation:
Answer:
x = 12
Step-by-step explanation:
Δ ESR and Δ EGF are similar, then ratios of corresponding sides are equal, so
= 
, substitute values
= 
( cross- multiply )
55(12x - 3) = 6435 ( divide both sides by 55 )
12x - 3 = 117 ( add 3 to both sides )
12x = 120 ( divide both sides by 12 )
x = 10
