Write an equivalent expression for 10x + 2 using the distributive property. a. x(10 + 2) b. 10(x + 2) c. 2(x + 2) d. 2(5x + 1)

The greatest common factor for 10x and 2  is so we take out 2 to give:_

2(5x + 1)

Its D

D because 2•5x=10 then 2•1= 2

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
