The Gcf of 18m x 18m and 7m is 1
My guess is SAS, it’s definitely not a or d
Since A is to the right of B, that means A is larger than B, so #1 is "A>B"
Since -A is to the left of -B, that means -A is smaller than -B, so #2 is "-A<-B"
First, distribute 2 to all terms within the parenthesis
2(4x + 5) = 8x + 10
8x + 10 > 7x + 20
Isolate the x. Treat the > like a equal sign. Subtract 7x and 10 from both sides
8x (-7x) + 10 (-10) > 7x (-7x) + 20 (-10)
Simplify
8x - 7x > 20 - 10
x > 10
x > 10 is your answer
hope this helps
