Find the highest common factor (H.C.F) OF 168 and 252.

blondinia [14]

Let's first write all the factors of 168 and 252.

168 - <span>1,2,3,4,6,7,8,12,14,21,24,28,42,56,84,168</span>
252 - 1,2,3,4,6,7,9,12,14,18,21,28,36,42,63,84,126,252

84 is the GCF because 84 is greatest common factor of 168 and 252.

So, 84 is the GCF

Hope this helps.. :)

(a+7)2<br> please expand it

sergiy2304 [10]

Answer:

expand (a + 7) * 2: 2a + 14

Step-by-step explanation:

(a + 7) * 2

= 2 ( a + 7)

apply the distributive law: a(b + c) = ab + ac

a = 2, b = a, c = 7

= 2a + 2 * 7

multiply the numbers: 2 * 7 = 14

= 2a + 14
