Answer:
The width of the piece of construction paper is 6.75 inches.
Step-by-step explanation:
The area of the paper =
sq inches
The length of the paper =
in
Let the width of the paper = w inches
Now, AREA OF THE PAPER = LENGTH x WIDTH
or, 65.25 sq. inches = 9. 66 in x w in
⇒ 65.25 = 9.66 x w
or, 
or, w = 6. 75 inches
Hence, the width of the piece of construction paper is 6.75 inches.

Answer:
Option C
Step-by-step explanation:

Lets convert it into improper fraction.

Lets convert
into a mixed fraction.

Rounding off 7.04 gives 7 and rounding 7 further gives 10.
So , the estimate of the product is 10
f(x) = 3/(x + 2) - √x - 3
f(7) = 3/(7 + 2) - √7 - 3
f(7) = 3/9 - √4
f(7) = 0.333 - 2
f(7) = -1.67
