ABC is isosceles with AB=AC=8 units and BC=6 units. D and E are midpoints of AB and BC respectively. Calculate the length of DE?

Allushta [10]

The triangle is drawn and is shown in the image attached with.

We get two similar triangles. Triangle ABC and Triangle ADE. Since the triangles are similar the ratio of their corresponding sides will be the same.

D and E are the midpoints of AB and BC, therefore, AD and AE are both 4 units in length. Using the property of similar triangles, we can say:

AD : DE= AB : BC
AD = 4 units
AB = 8 units
BC = 6 units
DE = unknown = x units

So,

$4 :x = 8 : 6 \\ \\ 
 \frac{4}{x} = \frac{8}{6} \\ \\ 
x=4* \frac{6}{8}=3 
$

Therefore, the length of DE will be 3 units

Solve 5x(m+n) using the distributive property

Genrish500 [490]

Answer: $5xm+5xn$

Step-by-step explanation:

For this exercise it is necessary to remember the following:

1) The Distributive Property states the following:

$a(b+c)=ab+ac\\\\a(b-c)=ab-ac$

2) The multiplication of signs:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-$

Knowing this, and having the following expression given in the exercise:

$5x(m+n)$

You can apply the Distributive property multiplying $m$ and $n$ , which are inside the parentheses, by $5x$ .

So, you get the following result:

$=(5x)(m)+(5x)(n)=5xm+5xn$

Please help,I don’t get this and my friends also need your help

ira [324]

STEP 1:
Add the number of total students
= 27+25+23
=75

STEP 2:
Find the percentage that 18 out of 75 students is.

18/75=x/100

cross multiply
(18*100)=(75*x)

1800=75x
divide both sides by 75
24%=x

Check:
75 * 24%= 18

Hope this helps! :) Good luck!
