Answer 2

I can answer your question in detail. 0.8t4 + 2.4c - 2.1t4 is a polynomial expression with three terms. To simplify it, we can combine the terms that have the same variable and exponent. In this case, the terms 0.8t4 and -2.1t4 have the same variable t and the same exponent 4, so we can add them together. To do this, we add the coefficients of these terms, which are 0.8 and -2.1. The result is -1.3. Therefore, we can write 0.8t4 + 2.4c - 2.1t4 as -1.3t4 + 2.4c. This is the simplest form of the expression.
