s=√(13.5-12)(13.5-9)(13.5-6)

s=√(1.5)(4.5)(7.5)

Answer:

A) $T=\frac{-20}{4}$

B) T = -5 °C

Step-by-step explanation:

A) Let T be the change in temperature of the week. T is determined as the total temperature change (-20°C) divided by the number of weeks that have passed (4 weeks). The expression is:

$T=\frac{-20}{4}$

B) In order to simplify the expression, simply perform the division.

$T=\frac{-20}{4}\\T=-5^oC$

This means that the temperature has dropped by 5 degrees each week.
