The factorization: (x-9) (x+12) (AC method)
X intercepts: (9,0), (-12,0)
Y intercepts: (0, -108)
Every angle of a square equals 90 degrees.
2x - 4 = 90 3y + 6 = 90
2x = 90 + 4 3y = 90 - 6
2x = 94 3y = 84
x = 94/2 y = 84/3
x = 47 y = 28
so x = 47 and y = 28
x+x+y.y.y = 2x+y^3 ( y cube)
So, The answer is (d)
Answer:
b
Step-by-step explanation:
Answer:
Step-by-step explanation:
19. 18-4.62=13.38 to spend on the systems or 6.69 a piece
20. 45000+300m=60000
m=50
45000+300m>60000
He needs at least 50 machines to make the 60000.
