Answer: X+5

Step-by-step explanation:

When you take out the 9 it should be 9(x+5) and when you take out the 9x on the bottom it gives you (x+5)+20 therefore x+5 is your GCF.

I hope this helps :)

Find the coordinates of the point P that lies

victus00 [196]

The coordinates of point P are: (1/5 , -12/5)

Step-by-step explanation:

Here

R(-3,-4) = (x1,y1)

S(5,0) = (x2,y2)

The ratio is: 2:3

The coordinates of a point that divides the line in ratio m:n are given by:

Let P be the point then

$(x_P, y_P) = (\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n})$

Putting values

$(x_P, y_P) = (\frac{(2)(5)+(3)(-3)}{2+3},\frac{(2)(0)+(3)(-4)}{2+3})\\= (\frac{10-9}{5},\frac{0-12}{5})\\=(\frac{1}{5},\frac{-12}{5})$

Hence,

The coordinates of point P are: (1/5 , -12/5)

BD = 21 m. BC= 25 m. DE = 40 m. AB = 7m. Find AB

Cloud [144]

Given:

Let us consider the given sides are:

$BD=21m$

$BC=25m$

$DE=40m$

$AB=xm$

To find:

The length of side AB.

Solution:

Suppose the measure of AB be x.

From the given figure it is clear that,

$\angle ADE \cong \angle ABC$ (Right angles)

$\angle ADE \cong \angle ABC$ (Corresponding angles)

In triangles ABC and ADE, two corresponding angles are congruent. So, by AA property of similarity,

$\Delta ABC\sim \Delta ADE$

We know that, corresponding sides of similar triangle are proportional.

$\dfrac{AB}{BC}=\dfrac{AD}{DE}$

$\dfrac{x}{25}=\dfrac{(x+21)}{40}$

$40x=25(x+21)$

$40x=25x+525$

Isolating the x terms, we get

$40x-25x=525$

$15x=525$

$x=\dfrac{525}{15}$

$x=35$

Hence, the measure of AB is 35 m.
