We can use the distributive property to simplify this expression.

I split this up into different parts--it helps me visualize better.

To begin, "-2m(m + n - 4)" becomes "-2m^2 - 2mn + 8m"

Then, "5(-2m + 2n)" becomes "-10m + 10n"

Finally, "n(m + 4n - 5)" becomes "mn + 4n^2 -n"

We can then simplify even further by combining like terms. The final expression is: C

Hope this helps!

During the summer, Cecile read twice as many books as Kami. Laura read three times as
Eva8 [605]

Answer:

The equation

c x 2 > k

l x 3 ?> c > k

g = 30 = c + l + k

this equation is the same as...

Cecile read twice as many books as Kami.

Laura read 3 times as many books as Kami, but possibly less than Cecile.

Gigi read 30 books. 30 books is the same as all 3 girls combined.

To find out how many books each girl read, you need to find 3 unequal numbers that add up to 30. These numbers are substituted, only because they can be anything at all, and I want to prevent confusions.

hope this helps!

Find the height of a tree of angle of elevation of its top changes from 25 degree to 50 degree as the observer advance 15m towar
Natali5045456 [20]

Answer:

  11.5 m

Step-by-step explanation:

The problem can be solved using a trig relation that relates the side opposite the angle to the side adjacent to the angle. That relation is ...

  Tan = Opposite/Adjacent

The lengths of the adjacent sides of the triangle can be found by rearranging this formula:

  Adjacent = Opposite/Tan

__

The "opposite" side of the triangle is the height of the tree, which we can represent using h. The problem statement tells us of a relation between adjacent side lengths and angles:

  h/tan(25°) -h/tan(50°) = 15 . . . . . moving 15 meters changes the angle

  h(1/tan(25°) -1/tan(50°)) = 15

  h = 15·tan(25°)·tan(50°)/(tan(50°) -tan(25°)) = 15(0.55572/0.72545)

  h ≈ 11.4907 . . . . meters

The height of the tree is about 11.5 meters.
