Answer:
Ok so the area of the frame is 18*12 = 216cm^2
Let’s suppose the width of the frame is x
The total area (painting and frame) is (2x+18)(2x+12) and this is equal to 432
4x^2 + 60x + 216 = 432
4x^2 + 60x - 216 = 0
x^2 + 15x - 54 = 0
(x+18)(x-3) = 0
Therefore x = {-18,3}
Since width of the frame has to be positive, the width has to be 3cm Step-

5×(3-2)=5×1=5
or
5×3+5×(-2)=15+(-10)=15-10=5
To solve this problem, work out the problem normally as if the "≥" is "=".
3.1v - 1.4 ≥ 1.3v + 6.7
-1.3v -1.3v
________________
1.8v - 1.4 ≥ 6.7
+1.4 +1.4
________________
1.8v ≥ 8.1
___ ___
1.8 1.8
v ≥ 4.5, is the answer.
