sqrt(7) = 2.645
so it falls between 2 and 3
1-4 I think because the larger arrow is at -4 and smaller is at 1
First you need to distribute the negative to 5,3x and -4 now you have this:
-3.5x+7-5.3x +4 rearrange and combine like terms (matching x's with x's etc.)
-3,5x -5.3x +7+4
-8.8x +11 your final answer there are no more like terms that you can combine.
Step-by-step explanation:
The exterior angles of an equilateral triangle will always have a measure of 120°.
