To factor the expression \(20u + 35\), we first find the greatest common factor (GCF) of the coefficients 20 and 35.
The factors of 20 are: \(1, 2, 4, 5, 10, 20\).
The factors of 35 are: \(1, 5, 7, 35\).
The greatest common factor is \(5\).
Now, we can factor out \(5\) from the expression:
\[ 20u + 35 = 5(4u) + 5(7) = 5(4u + 7) \]
Thus, the factored form of \(20u + 35\) is:
\[ 5(4u + 7) \]
This answer is a product with a whole number greater than 1.
