2:4:6 =2x :4x :6x
2x -1st angle
4x -2d one
6x - 3d one
2x+4x+6x=180 because MNO is a triangle
12x=180
x=180/12=15
2*15=30° -1st angle
4*15= 60° -2d one
6*15=90° - 3d one
Answer:
4a(5a + 1)
Step-by-step explanation:
Given
20a² + 4a ← factor out 4a from each term
= 4a(5a + 1)
Answer:
B
Step-by-step explanation:
58×20=1160
0+160+1000=1160
The answer is D. The ones on the left are the domain. The ones on the right which the arrows point to are the range
Just divide 5/4 = 1.25. Thank you.
