Question

What is the equivalent form of the mathematical expression 14 + 35?

10(4 + 15)

14(1 + 21)

7(2 + 5)

2(7 + 17)​

Answer 1

7(2 + 5)

Explanation:

If you factorise 7 out of '14 + 35' (because both numbers are divisible by 7):

• 14 ÷ 7 = 2
• 35 ÷ 7 = 5

This becomes 7(2 + 5). (7 × 2 is 14 and 7 × 5 is 35 which makes 14 + 35).

Hope this helps!
