2x^2 - 3 = -4x - 1
2x^2 + 4x - 3 + 1 = 0
2^2 + 4x - 2 = 0 <==
Answer:
perimeter: 90z+176
Explanation:
perimeter = measure of all length sides
perimeter for this shape:
45z + 40 + 15z + 48 + 20z + 60 + 10z + 28
group terms like this ↓
45z+15z+20z+10z+40+48+60+28
addition of terms ↓
45z+15z+20z+10z+176
this is how final result would look ↓
90z+176
Answer:
6 possible combinations
Step-by-step explanation:
In order to find the total number of combinations that he can choose from we simply need to multiply the number of options that each beverage has by each other. For example, there are 2 different types of milk and 3 different types of juice. Therefore, we would do...
2 * 3 = 6 combinations
Finally, we can see that Erik has a total of 6 possible combinations that he can choose from when buying the milk and juice.
Answer:
1 is 5+2a =7 and 2is 14+3a=3 and 3 is 7-2a=5
Answer:
C
Step-by-step explanation:
A system of equations has infinitely many solutions when the two lines representing the equations coincide. i.e. the two equations are the same or a multiple of each other.
2y - 4x = 6
2y = 4x + 6
2y = 2(2x + 3)
y = 2x + 3
-y = -(2x + 3)
-y = -2x - 3
Hence the other equation is -y = -2x - 3
