Answer:

11, 23, 19

Step-by-step explanation:

P535369b=a+b+c=(b−12)+b+(b−4)=3b−16=3b=23

The length of the second side is 23 feet. Substituting this back into the expressions for the lengths of the first and third sides, we find

1st side=b−12=23−12=11 3rd side=b−4=23−4=19

The three sides are 11, 23, and 19.

Let the shortest side be = a, then side b = 2·a and side c = (b + 24)

We are given that a + b + c = 84

Substituting for b and c

a + 2·a + (a + 24) = 84

4·a + 24 = 84

4·a = 84 - 24 = 60

a = 60/4 = 15 feet

b = 2·15 = 30 feet

c = 15 + 24 = 39 feet


sorry if i am wrong

ankita and her three friends are going to share a three bedroom apartment if the total rent is Rp.r, what is ankitas share
Alik [6]

Using proportions, it is found that Ankita's share is of \frac{x}{4}, considering that the total rent is of x Rp.r.

  • This question is solved by <em>proportions</em>, using a rule of three.
  • Considering that there are 4 people and the rent is of x Rp.r, 4 people pay x, how much does Ankita, which is one person, pay?

The <em>rule of three</em> is:

4 people - x

1 people - a

Applying cross multiplication:

4a = x

a = \frac{x}{4}

Ankita's share is of \frac{x}{4}, considering that the total rent is of x Rp.r.
