None. Because when you solve for x, x is eliminated.
It is 5
2x2 -4x +6-1= 0 is the standard form
Answer:
Step-by-step explanation:
If cost price (CP) is greater than selling price (SP) , then the item is sold for loss.
Loss = CP - SP
Loss% = 
If SP is greater than Cp, then the item is sold for a profit.
Profit =SP -CP
Gain % = 
a) CP = $50 ; SP = $30 ; CP > SP, loss
Loss = 50 - 30 = $ 20
Loss % = 
= 40% loss
b) CP = £ 5000 ; SP = £6250 ; SP > CP , Profit
Profit = 6250 - 5000 = £ 1250
Profit % = 
25% Profit

Solution (a):</h3>
- Area of rectangle = LB
- => Area of rectangle = 18 x 36
- => Area of rectangle = 648 in²
<h3>
</h3><h3>
Solution (b):</h3>
<u>Since the two triangles are equal (as said in the question):</u>
- => Area of triangles: 2(1/2 x 6 x 18)
- => Area of triangles: 6 x 18
- => Area of triangles: 108 in²
<h3 /><h3>Solution (c):</h3>
<u>Subtract the area of the triangles from the area of the rectangle.</u>
- 648 - 108 = Area of trapezoid
- => 540 in² = Area of trapezoid
