Answer:
pretty sure its B
Step-by-step explanation:
Because all angles adds up to 180 we are going to add the equations and equal it to 180.
5x - 3 + 4x - 7 + x = 180
5x + 4x + x - 3 - 7 = 180
10x - 10 = 180
10x = 180 + 10
10x / 10 = 190/10
x = 19 degrees
5x - 3
5(19) - 3 = 92 degrees
4x - 7
4(19) - 7 = 69 degrees
angle L = 92 degrees
angle M = 69 degrees
angle N = 19 degrees
568 would be estimated to 570 for nearest tens or 600 for nearest hundreds
Is one piece good? and how long is it?
Answer:x
2−14x+40=0 Factor x2−14x+40 using the AC method.(x−10)(x−4)
0 If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.x−10=0x−4=0 Set the first factor equal to 0 and solve.x=10Set the next factor equal to 0and solve....x=4
The final solution is all the values that make (x−10)(x−4)=0 true x=10,4
