Question

solve the equation 4(p + 5) = 21.
21 is not evenly divisible by 4, so lets start by using the distributive property.
multiply each term in the parentheses by 4.
4(p + 5) = 21
□ +? = 21

Explanation:

Step1: Apply distributive property

The distributive property states that \(a(b + c)=ab+ac\). For the equation \(4(p + 5)=21\), we multiply 4 with \(p\) and 4 with 5. So, \(4\times p+4\times5 = 21\), which simplifies to \(4p + 20=21\). The first blank is \(4p\) and the second blank (the "?") is \(20\) (since \(4\times5 = 20\)).

Answer:

The value for "?" is \(20\)
