Molly and Nancy disagree about the value of the expression 2+3×4. Molly thinks it is 20 and Nancy thinks it is 14.how could
2 answers:
Molly- 2+3 equals 5 then she times that by 4 which gets 20 but Nancy used PEMDAS and did 4x3 then added 2 which gets 14. Nancy is correct
Molly : she calculated 2 + 3 x 4.....and she got 20......so she basically added 2 + 3 (which equals 5), then multiplied by 4...giving her 20. Nancy : she calculated 2 + 3 x 4...and she got 14...so she basically multiplied the 3 x 4 (which is 12) and added the 2. Nancy is correct because in PEMDAS (the order of operations) multiplication comes before addition

Answer:
g(x) = x^2 + 1
if x=1
g(1) = 1^2 + 1
g(1) = 1 + 1
g(1) = 2
2 consecutive even integers : x and x + 2 x + x + 2 = 170 2x + 2 = 170 2x = 170 - 2 2x = 168 x = 168/2 x = 84 x + 2 = 84 + 2 = 86 so ur 2 numbers are 84 and 86
