300 messages would have to be sent or received in order for the plan to cost same each month.
Step-by-step explanation:
Given,
Cost per month = $30
Per text sent or received charges = $0.10
Let,
x be the number of texts sent or received.
A(x) = 0.10x+30
A comparable plan costs = $60 per month
Text messages are unlimited.
B(x) = 60
For the two plans to cost equal;
A(x) = B(x)
![0.10x+30=60\\0.10x=60-30\\0.10x=30](https://tex.z-dn.net/?f=0.10x%2B30%3D60%5C%5C0.10x%3D60-30%5C%5C0.10x%3D30)
Dividing both sides by 0.10
![\frac{0.10x}{0.10}=\frac{30}{0.10}\\x=300](https://tex.z-dn.net/?f=%5Cfrac%7B0.10x%7D%7B0.10%7D%3D%5Cfrac%7B30%7D%7B0.10%7D%5C%5Cx%3D300)
300 messages would have to be sent or received in order for the plan to cost same each month.

Answer:
A.) (7t³ + 2k^4)(7t³ - 2k^4)
Step-by-step explanation:
Factor the following:
49 t^6 - 4 k^8
49 t^6 - 4 k^8 = (7 t^3)^2 - (2 k^4)^2:
(7 t^3)^2 - (2 k^4)^2
Factor the difference of two squares. (7 t^3)^2 - (2 k^4)^2 = (7 t^3 - 2 k^4) (7 t^3 + 2 k^4):
Answer: (7 t^3 - 2 k^4) (7 t^3 + 2 k^4)

Answer:
96
Step-by-step explanation:
once you fill in the Blanks that are solvable, you will work your way into the answer. For example, the first column, the missing number has to be 155-76 or 79. Now you can find your answer. In the second row, “no Laptop”, you have 79 (solved above) plus 17. So your answer is 79+17 or 96.
