Multiply both the numerator and denominator by , which is called the "conjugate" of :
Why do we pick this number? Recall the difference of squares factorization:
Now replace and . Then
So in your fraction, you end up with
Finally, just expand the product.
Answer:
260 im pretty sure
..........
if there is 5 or higher in the ones place you round up, if there's a 4 or lower you round down. Since there is a 0 in 260 it stays the same so the answer is 260

Step-by-step explanation:
Answer:
2. It will be a 7 3/4in x 12 1/4in rectangle
4. 31,987 in^2
6. 30 547/640 in^3
Step-by-step explanation:
2. This is a cross-section. In order to get the cross-section, you take your shape. (a 7 3/4 x 12 1/4 x 3 3/4 rectangle) and essentially you remove the last dimension (Height).
4. Take your surface area value (319 35/64) and multiply it by 100 (10 per dimension length and width). This leaves you with 319.87x100 = 31,987 in^2
6. (308 35/64)/10. Pretty easy, take 308.546875, divide by 10, and you get 30.8546875, which is 30 547/640 in^3 in fractions.
