Aline parallel to a triangle’s side splits one side into lengths of 9 and 3. the other side is split into lengths of 12 and x. what is the value of x? (enter the number only)

The value of x = 4.

Step-by-step explanation:

As per figure attached line DE is parallel to BC.

DE splits line AB into lengths 9 and 3.Similarly splits the other side AC of the triangle into 12 and x.

Now we can see that ΔABC and ΔADE are similar because they follow the rule all angles of ΔABC are same of ΔADE.

Therefore

⇒

Now we cross multiply the fractions of both the sides.

9(x+12) = 12×12

9x+108 = 144

9x+108-108 = 144-108

9x = 36

x = 4.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

51-50
