Answer: x>-1
x<-3
Step-by-step explanation:
subtract 3 on both sides
divide -2 on both sides
The sign changed because I divided by a negative.
add 3 on both sides
multiply -1 on both sides
divide 4 on both sides

Step-by-step explanation:
This triangle is a polygon. By definition, all the exterior angles of ANY polygon add up to equal 360 degrees. So we add up all the exterior angles and solve for x. That's the first step.
7x - 2 + 9x - 31 + 4x + 33 = 360
Combining like terms gives us
20x + 0 = 360 or simply
20x = 360 so
x = 18
In order to find the value of the angle exterior to angle C, we sub 18 in for x:
7(18) - 2 = 124
Answer:
a -25/6 is the least and then -2/3 then 1 1/6 and 1 15/6
Answer:
6 m, 6 m, 5 m
Step-by-step explanation:
If x is the common length then the perimeter is the sum of side lengths:
x + x + (2x-7) = 17
4x = 24 . . . . . . . . . add 7
x = 6 . . . . . . . . . . divide by 4
2x -7 = 12 -7 = 5 . . . find the length of the 3rd side
The side lengths are 6 m, 6 m, and 5 m.
