(X - 3)+(2x + 8)+(2x) = 180
5x + 5 = 180
5x = 175
X = 35
Answer: m = 16
Remember: the base angles of a trapezoid are congruent.
Form your equation.
4m + 1 = 2m + 33
Solve for m.
4m + 1 = 2m + 33 Subtract 1 from both sides
4m = 2m + 32 Subtract 2m from both sides
2m = 32 Divide by 2 to both sides
m = 16 Answer!
You can also check your work.
4(16) + 1 = 2(16) + 33
64 + 1 = 32 + 33
65 = 65

Step-by-step explanation:
You are doing simple math within the square root. For instance where x=-2 you substitute -2 for x then add 2 which gives you 0 leaving you with -6.
for x=2 you end up with "square root 2+2" which gives you 4 and the square root of 4 is 2 so you add -6 to 2 giving you the answer of -4.
Answer:
50 laps
Step-by-step explanation:
20+1.25x+15+2.5x+40+1.5x+25+1.75x=450
7x+100=450
7x+200-200=450-100
7x=350
7x/7=350/7
x=50
