I think the answer is 300 because 4 is less tvhan 5 and when you round numbers, if the number is less than you leave it or if it is 5 or more you add one more.
The are is the whole area minus the inner:
(z+4)(z+4)-(z)(z)
Expand:
z^2+8z+16-z^2
Simplify:
8z+16
Answer:
8z+16 OR 8(z+2)
Answer:
1.5 inches
Step-by-step explanation:
Because the base of the notepad is a square, that means that each side of the base would be equal. Since the area is 2.25 square inches, and each side would have to be equal, the equation to solve would be x*x = 2.25, or x^2=2.25. So, you just take the square root of both sides, and x=1.5 inches. Each side of the notepad would be 1.5 inches.
