The expression 8x+2 factored using gcf

2* (4x + 1)

Step-by-step explanation:

8x = 2 * 2 *2 * x

2 = 2* 1

GCF = 2

8x+2  =  2*2*2*x + 2*1 = 2* (4x + 1)

Step-by-step explanation:

4+2S=12+S

in the left side there is one triangle so its value is 4 and two square so its value is 2S because you don't know the value of the square.

In the right side, there is 3 Triangles and one square so its value is 12 (3*4)+S

So,           S=8

how?

12+4=16

S=16/2=8
