Step-by-step explanation:
a. a^4 - 2ab^2 - 2ab^2 + 4b^4 = a^4 - 4ab^2 + 4b^2
b. 49x^2 - 14x + 1
c. 25a^2 - 20ab^4 + 4b^8
d. x^2 - 144
e. -16n^6 - 28n^3 + 28n^3 + 49 = -16n^6 + 49

Answer:
$13.62
Step-by-step explanation:
By working backward we can see that before she cleaned the windows she had $6.81.
We know that she spent half her allowance on the arcade and the $6.81 she had before cleaning the windows is the other half.
So, if you multiply by 2 you get that here weekly allowance is $13.62.
We want to write an inequality that reflects that you can spend between $150 and $450.
We will find the inequality:
450 ≥ 11*t + 18 ≥ 150
And solving this we have:
39.3 ≥ t ≥ 12
Now let's see how to solve this problem.
So, we start with the inequality:
150 ≥ 11*t + 18.
I assume that:
11*t + 18
Is the amount you will spend, and 150 is the initial maximum amount that you can spend.
Now your parents give you $300, so the maximum goes from $150 to $450, and we also have a minimum of $150 (because the problem says it).
Then we write the inequality as:
450 ≥ 11*t + 18 ≥ 150
We can solve this for t:
450 - 18 ≥ 11*t ≥ 150 - 18
432 ≥ 11*t ≥ 132
432/11 ≥ t ≥ 132/11
39.3 ≥ t ≥ 12

Always know the formula for volume prism because that shape is a prism.
Formula For PRISM: BH/2 x Height.
So then we are going to solve the triangle first... 7 x 22= 154/2= 77
Then multiply by the height which is 25.
77 x 25= 1,925.
So your answer should be 1,925 meters cubed. *Don't forget to write the measurement
*hope this helps
