Question

factor 40 + 64. write your answer in the form a(b + c) where a is the gcf of 40 and 64.

Explanation:

Step1: Find GCF of 40 and 64

Factors of 40: \(1, 2, 4, 5, 8, 10, 20, 40\)
Factors of 64: \(1, 2, 4, 8, 16, 32, 64\)
GCF is \(8\).

Step2: Divide terms by GCF

\(40 \div 8 = 5\), \(64 \div 8 = 8\)

Step3: Write in \(a(b + c)\) form

Substitute \(a = 8\), \(b = 5\), \(c = 8\): \(8(5 + 8)\)

Answer:

\(8(5 + 8)\)
