Answer:
Step-by-step explanation:
1*12 + 2*2 + 3*6 = 12 + 4 +18 = $34
x^2 + 2xy + y^2 - m^2
= (x+y)^2-m^2
Answer: C
Step-by-step explanation: since he has 4 dice, there are 24 chances. But he needs 2 fives. That means 2/24 = 1/13. 1/13= C
y = 7x - 4
point: (0, -4)
slope: 7
use point-slope form
y-(-4) = 7(x-0)
y+4 = 7x
(x-1) (x+5)
