Answer:
10 cm
Step-by-step explanation:
a^2 + b^2 =c^2
6^2 + 8^2 = c^2
36 + 64 = 100
then find the square root of 100 which equals 10
7/12 times 4 is 2 1/3. So 2 1/3 inches each week

Plug in x = 2:

Multiply:

Subtract 4 to both sides:

Divide 3 to both sides:

So our solution is
The temperature rose, which means it increased. An increase is a positive value, so add a plus sign in front of the number: +4
A decrease is a negative value, so add a negative sign in front of the value: -19
