Answer:
-12°F
Step-by-step explanation:
2 P.M
-35° F + 29° F= -6° F
The temperature had risen by 29°F meaning it went up by 29.
Adding negative 35 and positive 29 is the same as subtracting 35 from 29.
29 - 35 = -6
6 P.M
-6° F - 18°F = -12°F
The temperature had fallen by 18°F meaning it went down by 18°F.
p.s don't forget the label °F

next year (both ages increased by 1)
megan's age and mom's age will be perfect square
k+1=r²
m+1=c²
where c and r are whole numbers
ok, one way is to list all the perfect squares, decrease them by 1 and find which ones are double of another perfec tsquare
0,1,4,9,16,25,36,49,64,81,100
decrease by 1
-1,0,3,8,15,24,35,48,63,80,99
ah, 24 and 48
