Use a Vertical Format to Add the Polynomials $$\begin{array} { r r } 1.5 x ^ { 3 } + 7.7 x ^ { 2 } + & 4.1 \\&- 3.4 x - 2.7 \\- 3.5 x ^ { 2 } + & x + 9.7 \\\hline\end{array}$$

question 5

Multiple Choice

Use a vertical format to add the polynomials.
- $$\begin{array} { r r } 1.5 x ^ { 3 } + 7.7 x ^ { 2 } + & 4.1 \\&- 3.4 x - 2.7 \\- 3.5 x ^ { 2 } + & x + 9.7 \\\hline\end{array}$$

• A) \(1.5 x ^ { 3 } + 11.2 x ^ { 2 } + 5.4 x - 8.3\)
• B) \(13.1 x ^ { 6 } + 11.1\)
• C) \(1.5 \mathrm { x } ^ { 3 } + 4.2 \mathrm { x } ^ { 2 } + 6.4 \mathrm { x } + 11.1\)
• D) \(1.5 \mathrm { x } ^ { 3 } + 4.2 \mathrm { x } ^ { 2 } + 7.4 \mathrm { x } + 11.1\)

A stimulus that has become rewarding through its association with a primary reinforcer.

Negative Reinforcer

An unpleasant or aversive stimulus that, when removed or avoided following a behavior, increases the likelihood of that behavior being repeated.

Positive Reinforcer

A stimulus which, when presented after a behavior, increases the likelihood of that behavior being repeated.

Positive Punisher

A stimulus that, when introduced after a behavior, decreases the likelihood of that behavior occurring again.
