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

You can use the commutative property to reorder the terms of an expression. James says that you can use the commutative property
Rashid [163]

By the commutative property of addition, Jame's claim is incorrect

<h3>What is the commutative property?</h3>

The commutative property of addition states that:

a + b = b + a

The expression is given as:

5m + 10

The equivalent expression is:

10 + 5m

This is properly represented as:

5m + 10 = 10 + 5m

Jame's claim can be represented as:

5m + 10 = 10m + 5

The above equation is not correct, for the commutative property of addition.

Hence, Jame's claim is incorrect
