If the price went down $5 per day for four days straight, then it would have went down $20 total after the four days.
Replace the x and y and the answer would be A
3(2x+1)=2(x+1)+1
Step 1:Simplify both sides of the equation
(3)(2x)+(3)(1)=(2)(x)+(2)(1)+ -(distribute)
6x+3=2x+2+1
6x+3=(2x)+(2+1) -(Combine Like Terms)
6x+3=2x+3
Step 2: Subtract 2x from both sides
6x+3-2x=2x+3-2x
4x+3-3=3-3
4x÷4=0÷4
x=0
Area = 1/2(Base * Height)
Area = 1/2(6*20) = 60m^2
the area of the triangle is 60m^2
