Answer:
C. ![\displaystyle 4x^2 - 20x + 26](https://tex.z-dn.net/?f=%5Cdisplaystyle%204x%5E2%20-%2020x%20%2B%2026)
Step-by-step explanation:
![\displaystyle [2x - 5]^2 + 1 = [2x - 5][2x - 5] + 1 = 4x^2 - 20x + 25 + 1 = 4x^2 - 20x + 26](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5B2x%20-%205%5D%5E2%20%2B%201%20%3D%20%5B2x%20-%205%5D%5B2x%20-%205%5D%20%2B%201%20%3D%204x%5E2%20-%2020x%20%2B%2025%20%2B%201%20%3D%204x%5E2%20-%2020x%20%2B%2026)
In compositional functions, you always take the function inside parentheses FIRST, inputting that into the second function for every <em>x</em><em> </em>visible.

The student will have $135 in her bank account at the end of the ninth week. You can fine this out by finding out the amount she deposits a week and to do this you would take the $30 and divide it by 2 because she had $30 at the end of the second week.
30/2=15
So you see that the student deposits $15 each week, so to find out how much money she will have in 9 weeks you will multiply her $15 by 9.
15x9=135
So the student will have $135 at the end of the ninth week.
the area in square feet is 4400. (because to find the area of the rectangle you multiply the 2 side lengths, 100 and 80 which gives you 8000, then you find the area of the square, multiply 60 by 60 which is 3600, then you subtract the total area of the backyard by the area taken up by the garden, 8000-3600, which gives you your total of 4400.)
Answer:Her score is 26
Step-by-step explanation:
To find the answer, we must deduct the total amount of points that are answered correctly
By the total amount of points that are answered incorrectly.
Because = 1 answered correctly = 4 points
= 1 answered incorrectly = deduct 7
points
So= 87 answered correctly × 4 points
= 348 points
So= 46 answered incorrectly × 7 points
=deduct 322 points
Then the answer will be= 348 - 322= 26
Hope this helps!
