Answer:
Second step: 2/2 does not give you 2.
It would be 2x + 1 - 4 = 3x - 3
Since he mess up on the second step, the following steps are also messed up
Answer:
30 degrees
Step-by-step explanation:
I think that every corner is a 90 degree angle so 90/2 is 30
Answer:Do rise over run, maybe watch a tutorial on it, pretty simple method
a quadrilateral has 4 angles that add up to 360 degrees
x + 80+110+ 75 = 360
combine like terms
x + 265 = 360
subtract 265 from each side
x + 265 -265 =360 -265
x = 95
Choice C
It can be at least 5.4 feet long since the area of a square is A=s^2. 5.4 times 5.4 is 30
