3 small ones and 3 big ones because 3*7=21 plus 10*3=20 =51
(y+12)(y+12) is the answer
Answer:
Infinitely many
Step-by-step explanation:
2x + 2y = 8
x + y = 4
4x + 4y = 16
x + y = 4
Basically they represent the same line.
So all points on the line will satisfy both equations.
Hence infinitely many solutions
Step-by-step explanation:
=> x + 80 + 20 = 180
=> x + 100 = 180
=> x = 180 - 100
=> x = 80°
