Since you're adding x feet to the length which is 12 feet:
New area: (12+x)10.5
Answer: F
Step-by-step explanation: 90/3.28 equals 27.4390244
8 + 0.3 =
Standard . . . 8.3
Words . . . "eight and three tenths".
Answer:
Step-by-step explanation:
Let the width be w centimeters.
Then the length = w + 7.
The area A is found from the length multiplied by the width.
330 = w(w + 7) = w^2 + 7w.
Now we can rearrange this equation to form a quadratic, as follows:
The factorization of the quadratic is:
(w + 22)(w - 15) = 0
Therefore we find that:
width = 15 centimeters
length = 22 centimeters
