Detailed explanation:
Question 4 provides clear information,
thus resolving Question 4:
1 euro equals $1.17.
Consequently, €20.46 is calculated as 20.46 multiplied by 1.17, which equals $23.93.
1 pound equals $1.28.
Thus, £12.60 translates to 12.60 multiplied by 1.28, yielding $16.128.
Therefore, the MP3 in pounds is $7.81 cheaper in dollars.
X² + 7x - 8 = 0; product = -8 times 1 = -8; sum = 7; {-1, 8}; x² - 1x + 8x - 8 = 0; x(x - 1) + 8(x - 1) = 0; thus, x + 8 = 0 or x - 1 = 0, leading to x = -8.
The addition of the numbers can be done in any sequence.Step-by-step explanation:When determining the total time Colin spent traveling from home to the hotel, the sequence in which the numbers are added does not matter, since time is a scalar quantity that cannot be negative.A scalar quantity possesses only magnitude, without regard to direction. For instance, while temperature can be either positive or negative, time can only be positive, affirming its status as a scalar quantity.
