Step-by-step explanation:
the area of the square is (x+2)^2 and the factored form of it is x^2+4x+4
since we know the area is = 7 therefore
x^2 + 4x +4 = 7 and x^2 + 4x = 3
if you want to find the value of x :
x^2+4x+4 = 7
x^2+4x -3 = 0
(x-3)(x-1)=0
x = 3 or
x = 1
Answer: The managers statment would most likely give the valid interpretation.
Step-by-step explanation: If the store manager is 95% confident that the average amount spent was between $31.84 and $38.66. Then the store manager is most likey correct so I would have to say I agree with the manager. This may be a tricky question at first, but look at the problem from a different perspective. I am very sorry if this happens to be wrong.
