Estimating the area:
x = (20 \times 8)(13 \times 8) \\  x = 264
Calculating wallpaper:
x = (264 \times 1.05) \div 35 \\ x = 7.92 \\ x = 8
we round up here because they will need a full roll to complete the room. Since they can't buy 7.92 rolls, they must buy 8.

Calculating cost:
x = 8(31.48) + 31.48(0.0825) \\  x = 254.44

The sum of three consecutive integers is greater than 66. What is the smallest possible product of the largest and smallest of t
AysviL [449]

Answer:

528

Step-by-step explanation:

So naturally at first sight for this question we would think -->

Oh 3 consecutive integers = 66 --> 66/3 = 22 (n-1), (n+1) so --> 21, 22, and 23.

But no. At second look it is the sum of 3 consecutive integers is greater than 66. So we find the next possible pair since it says smallest possible product.

We get the set (22, 23, 24). => Multiply the least and greatest integers together respectively 22 and 24 which amounts to => 528

And thus, we have out answer of 528

Hope this helps!
