Jamar's teacher told him that one of the reasons he gave on the proof below was incorrect. Which reason did he make the mistake

Kamila [148]

Answer:

Reason given in step 2. is incorrect. It should read; "Distributive Property."

Step-by-step explanation:

The reason given to go from :

2 (3x +4) = 56 to 6x + 8 = 56

is NOT "Multiplication Property of Equality" because one is not multiplying both sides of the equality by a number. The property that is being used is the Distributive Property on the left side of the equation in order to remove the grouping symbols (parenthesis) performing the implied multiplication of the external factor times each term of the binomial in parenthesis.

The number of bacteria (b) in a batch of refrigerated food is given by the function b(t) = 20t2 − 70t + 300, where t is the temp

Setler79 [48]

If the number of bacteria $b(t)$ is a function only of temperature $t$ , and the temperature $t(h)$ is a function only of time in hours $h$ , then

$b(t(h))=b(2h+3)=20(2h+3)^4-70(2h+3)+300$
$b(t(h))=320h^4+1920h^3+4320h^2+4180h+1710$
