Answer:
First way: m+7m+m+7m
Second way: m(1+7+1+7) (factorize)
Third way: 2(m)+2(7m)
it should be step 2
Step-by-step explanation:
x = -2.9
y = 2.6
x+y = -2.9+2.6
= -0.3
49.4 degrees
SOHCAHTOA
tan x = opposite / adjacent
tan x = 7 / 6
using graphing calculator, you get x = 49.398 round to tenth = 49.4 degrees

9x + 9y
9(10) + 9(9)
