Answer:
Sarah bought 30 pencils
Step-by-step explanation:
1. Let define p, as the number of pencils bought, and m, as the number of markers bought.
2.
3. Substitute p in the first equation to 3m since p=3m as defined.
plug m into equation p=3m to find the number of pencils bought
3. tan(α) = height/distance
distance = height/tan(α)
distance = (648 m)/tan(13°) ≈ 1399.5 m
6. when y = |x| is translated 6 units down, 6 is subtracted from the y-value:
.. y = |x| -6
10. In point-slope form, the line through point (h, k) with slope m is
.. y -k = m(x -h)
For (h, k) = (10, -9) and m = -2, you have
.. y +9 = -2(x -10)

Answer:
L: (15+6x) W: 2
L: (10+4x) W: 3
L: (5+2x) W: 6
Step-by-step explanation:
We don't have any numbers here to do calculations, so probably this is just an exercise in FACTORING. Also to practice that area is length times width.
The area given,
30 + 12x
can be factored several ways to be able to fill in the table.
This kind of factoring is like "un-distributive property" where a common factor can be factored out of the expression. Usually its helpful to factor out the greatest common factor (GCF) but in this case any common factor will do.
Also, unless there are more directions, either factor may be the length or the width.
2(15+6x)
3(10+4x)
6(5+2x)
