Since the angles are supplementary (when added, equal 180°), you can add the two angles together to get (-18x)°. 180/-18 = -10 for x. Fill in -10 for x in both expressions. (-14 • -10)= 140° and (-4 • -10)- 40°. 140+40=180

Which expression represents the greatest common factor (GCF) of 70 and 112? A. 2 x 2 x 2 x 7 B. 2 x 2 x 2 x 5 C. 2 x 7 D. 2 x 2

Mekhanik [1.2K]

Answer:

$\huge\boxed{C. \ \ GCF = 2 * 7}$

Step-by-step explanation:

Firstly, we'll do prime factorization of these numbers.

70 = 2 × 5 × 7

112 = 2 × 2 × 2 × 2 × 7

So, The Greatest Common Factor can be written as:

GCF = 2 × 7 [Since Only one 2 and one 7 is common]

Hope this helped!
