Answer:
2np + p²
Step-by-step explanation:
The general formula for the area of a square is A = s², where s = the length of one side of the square. In the case of the smaller square the area would be: n x n = n². Since the side of the larger square is 'p' inches longer, the length of one side is 'n + p'. To find the area of the larger square, we have to take the length x length or (n +p)².
Using FOIL (forward, outside, inside, last):
(n + p)(n+p) = n² + 2np + p²
Since the area of the first triangle is n², we can subtract this amount from the area of the larger square to find out how many square inches greater the larger square area is.
n² + 2np + p² - n² = 2np + p²
The answer is 11

-x^2 + 7 is the simplified expression
What is the question it’s not showing
Answer:
4 1/2 hours
Step-by-step explanation:
To find how long, multiply the length of time in hours by the number of cakes. 1 cake takes 3/4 of a an hour so 6 cakes will take
3/4 * 6 = 18/4 = 4 2/4
4 2/4 simplifies to 4 1/2 hours.
