Answer:
12x⁴y⁴
Step-by-step explanation:
3xy + 3xy + 3xy + 3xy = 12x⁴y⁴
c/2-3+6/d
substitute c=14 and d=13:
14/2-3+6/13
simplify:
7-3+6/13
4+6/13
multiply 4 by 13/13 to group like terms (for a fraction):
52/13+6/13
combine:
58/13
Therefore, the answer is 58/13 or around 4.462
Answer:
A=-2; B=-1
Step-by-step explanation:
3a - 2b + 4 =0
2a -5b -1 = 0
Let's multiple the top equation by 2, and the bottom by -3, and then use addition.
[3a - 2b + 4 =0]*2
[2a -5b -1 = 0]*(-3)
6a-4b+8=0
-6a+15b+3=0
Now add the two equations together:
11b + 11 = 0
Subtract 11 from both sides
11b = -11
Divide both sides by 11
b=-1
Substitute in the first equation:
3a - 2(-1) + 4 = 0
Simplify to get 3a+6 = 0
Subtract 6 from both sides to get 3a = -6
Divide both sides by 3 to get a=-2
Step-by-step explanation:
y = 3x² - 10x - 2
a = 3
b = -10
c = -2
D = b² - 4ac
D = (-10)² - 4.3.(-2)
D = 100 + 24
D = 124
It would be 9. Because each person has to pay 4$ so 9*4=36 or 36/4=9
