Question

Which expression is equivalent to 20 - 35x ? *

Answer 1

5[4 - 7x]

Explanation:

Given expression:

20 - 35x

To factorize the expression, we need to determine the GCF of the terms.

• ⇒ 20 - 1, 2, 4, 5, 10, 20
• ⇒ 35x - 1, 5, 7, x, 35

Since "5" is the largest factor in both terms, the GCF is 5.

Factorize the expression using the GCF:

• ⇒ 20 - 35x
• ⇒ 5[(20 ÷ 5) - (35x ÷ 5)]
• ⇒ 5[(4) - (7x)]
• ⇒ 5[4 - 7x]

Thus, 5[4 - 7x] is equivalent to 20 - 35x.
