Answer:
9ab+3a
Step-by-step explanation:
(2a+a)(3b+1)=(3a)(3b+1)
3a(3b+1)
=(3a×3b)+3a×1
=9ab+3a
1/5/12 because,
3x4=12,4x2=8 witch would be 8/12 the 3x3=9+the 12=9/12. 9/12+8/12=1/5/12 so the path is 1/5/12.
Answer:
x = 45°
y = 15.41 units
Step-by-step explanation:
Given quadrilateral is a square. Each angle of square is 90°
Diagonal of square bisects the angle.
Step-by-step explanation:
(25x+8)°+(9x+2)°=180--->(1)(sum of angles on a straight line
(7y+5)°=(9x+2)°------------->(2)(vertical angles)
25x°+8°+9x°+2°=180°
34x°=170°
x=5°
from equation (2) substitute for x=5°
7y°+5°=9x°+2°
7y°+5°=9(5)°+2°
7y°=47°-5°
7y°=42°
y=6°
(x, y)=(5°,6°)
