Answer:
Step-by-step explanation:
200 * 42.3 = 200 * (40 + 2.3)
= 200*40 + 200*2.3
= 8000 + 460.0
=8460
I'm going to assume the 4 and 3 are exponents and the expression is
.
The first step is to separate the coefficients of 3 and -6 from the variables and to multiply those as normal:

As for the variables, you want to recognize that
means
and
means
, so

In total, there are 7 a's being multiplied, so

Putting this all together, we have:

The first one:))) Hope you do well
Answer: 26.55°C
Step-by-step explanation:
Average daily maximum temperature in Syracuse = 21.85°C
Average daily minimum temperature = -4.7°C
In order to solve the question, we calculate the difference between the two temperature given. This will be:
= 21.85°C - (-4.7°C)
= 21.85°C + 4.7°C
= 26.55°C
