Answer:
Yes, she has enough paint, since she does not need to paint the window. The area that needs to be painted is only 87 ft², and she has enough paint for 90 ft².
Step-by-step explanation:
Area of the wall (including window)
= 12 x 8
= 96 ft²
Area of the window
= 3 x 3
= 9 ft²
Area of the wall that needs to be covered with paint
= 96 - 9
= 87 ft²
Answer:
6.4 oz are left.
Step-by-step explanation:
Start with the bottle being half full.
A bottle that is half full when it started with 16 oz is 1/2 16 oz = 8 oz
If he drinks 1/5 of the remaining amount, it means that he has 4/5 left.
4/5 * 8 = 32/5 = 6.4 oz or 6 oz and 2/5 of an ounce.

Answer:
The answer is (C) Y = 3x² - 24x + 18
Step-by-step explanation:
Y = 3(x-4)² - 22
First step is to simplify (x-4)²
⇒ Y= 3(x-4)(x-4)-22
⇒ Y= 3(x²- 4x - 4x + 16) - 22 = 3(x² - 8x + 16) - 22
Next step is to open the parenthesis
⇒ Y = 3x² - 24x + 48 - 22
The final step is to collect like terms and simplify the equation
⇒ Y = 3x² - 24x + 26
