We can just use the remainder theorem here.
Plug the value of -2 into each x variable.
(-2)^3 - 1
-9
<h3>The remainder is -9.</h3>
<span>There are 144 square inches in a square foot. The cube you have has sides of 10 inches. First, find how many square feet are equal to one square inch (1/144, or 0.00694r). Then, multiply this by ten to tell you how many square feet you need to cover your cube. This makes 0.07 to two decimal places.</span>
Cool problem
x and y are the digits
x+y=11
yx=2(xy)+34
I'm not sure how to solve this using legit math so use trial and error
the 1 digit numbers that could be possible are
9,2
8,3
7,4
6,5
5,6
4,7
3,8
2,9
all of them add up to 11
the pairs obtained by swiching the number are
92 and 29
83 and 38
74 and 47
65 and 56
we find which ones are equal when we subtract 34 from the larger number and divide by 2
92-34=58
58/2=29
92 and 29 work
83-34=49
49/2=24.5 not equal to 38 not work
74-34=40
40/2=20 47 not equal to 20 so doesn't work
65-34=31
31/2=15.5 not equal to 56 so doesn't work
the origonal number is 29
No because if you were to square it you would get 5.099 and a perfect square is when it is the same number times each other to get a number for example: the square root of 9 is 3 so 3 times 3 is 9.
Hope that helps!
