Answer:
Step-by-step explanation:
hello :
(x-4)²(x+3)² = -1
means : ((x-4)(x+3))² = - 1 this equation has no solutions in R
because for all x in R : ((x-4)(x+3))² ≥ 0
Answer:
and 
Step-by-step explanation:
At=As+Ar; A=b.h and 
, then: At=(x+120)x so
(x+120)x=4500,

Answer:
Every 30 hours
Step-by-step explanation:
Train A arrives at central station on the hour and every 12 minutes, you mean with that on every 72 minutes
Train B arrives at central station on the hour and every 15 minutes, you mean with that on every 75 minutes
In accordance with the given, the smallest number containing numbers 72 and 75 is 1800 minutes.
When we convert this number of minutes in hours we get:
1800 / 60 = 30 hours

Answer: 22 small snow cones and 34 large snow cones were sold.
Step-by-step explanation:
Let x represent the number of small snow cones that were sold.
Let y represent the number of large snow cones that were sold.
Selena's snow cone stand sells small snow cones for $2 and large snow cones for $3.50. One summer day, she sold $163 worth of snow cones. This means that
2x + 3.5y = 163 - - - - - - - - - - 1
If the number of large snow cones sold was 12 more than the number of smalls snow cones, it means that
y = x + 12
Substituting y = x + 12 into equation 1, it becomes
2x + 3.5(x + 12) = 163
2x + 3.5x + 42 = 163
5.5x = 163 - 42
5.5x = 121
x = 121/.5 = 22
y = x + 12 = 22 + 12
y = 34
Answer:
It would be 35/36
Step-by-step explanation:
so if you did like 1+1, 1+2, 1+3....2+1,2+2, 2+3 yada yada
the only possible number combo that would equal twelve is 6+6 and there is 36 possible combos so your answer is 35/36
