2(3 + 9x) - 2x
= 6 + 9x - 2x <----------------mistake right here
= 6 + 7x
Correct:
Expanding by using distributive property
2(3 + 9x) - 2x
= 2* 3 + 2 * 9x - 2x
= 6 + 18x - 2x
= 6 + 16x
Answer:
The required number is 7.
Dividing by this gives the perfect square 676.
Step-by-step explanation:
Finding the prime factors:
2) 4732
2) 2366
7) 1183
13)169
13
So 4372
= 2^2 * 7 * 13^2
= 4 *169 * 7
= 676 * 7
Now 676 is a perfect square so the answer is 7.
= 1283 * 4.
Answer is 1283.
