Question

1. -4 + 8p - 6p - 5 + 20p

Explanation:

Step1: Combine constant terms

The constant terms are \(-4\) and \(-5\). So, \(-4 - 5=-9\)

Step2: Combine like terms with \(p\)

The terms with \(p\) are \(8p\), \(-6p\), and \(20p\). So, \(8p-6p + 20p=(8 - 6+20)p = 22p\)

Step3: Combine the results from Step1 and Step2

We get \(-9 + 22p\) or \(22p-9\)

Answer:

\(22p - 9\)
