Answer:
Fourteen 11th graders prefer math and eight 10th graders prefer science.
Answer:
63 I think
you can find a common denominator by multiplying the denominators together. however keep in mind that what you do to the bottom you must do to the top
1/7 would become 9/63 and 2/9 would become 14/63

Answer:
6 : 5
Step-by-step explanation:
The diagram shows you that the boxes have a length (L) to width (W) ratio such that ...
3L = <em>l</em> = 4W
L/W = 4/3
Suppose we call the width of the box 3 units, then its length is 4 units, and we have the crate dimensions ...
<em>l</em> = 4(3) = 3(4) = 12
<em>w</em> = 3+3+4 = 10
Then the ratio <em>l </em>: <em>w</em> is 12 : 10 = 6 : 5.

Step-by-step explanation:
How does y change as x increases over a range?
As x increases from -6 to -4, y decreases from 0 to -7
It is a decreasing function in this range and for ranges less than x = -6 as well as the slope is nearly constant
As x increases from -4 to 0, y increases from -7 to 4
It is an increasing function in this range.
For x increasing from zero, y becomes less and less
It is a decreasing function in the range larger than x = 0
Answer:
(x+y)² =(x+y)(x+y) Then you FOIL (First, outer, inner, last)
(x+y)² =(x+y)(x+y) = xx + xy + xy + yy [and when you combine like terms] = x² + 2xy + y²
(x+y)3 = (x² + 2xy + y²)(x+y) Then you FOIL (First, outer, inner, last)
(x+y)3 = (x² + 2xy + y²)(x+y) = x2x +2xxy + xy2 + x2y + 2xyy + y2y [and when you combine like terms] = x3 + 3x2y+ 3xy2 + y3
