We have a triangle whose perimeter is 32 feet. Some information regarding the sides of the triangle is given:
GiveN:
- One side is 3 times the second side.
- Third side is 12 feet longer than the second side.
As we can see that, two sides of the triangle are defined the second sides. It means First and third side can be expressed in the form of second side.
- So let the second side be x
Then,
- First side = 3x
- And, third side = x + 12
We know that, perimeters is the sum of the lengths of all sides of the triangle, So it can be written as:
![3x + x + x + 12 = 32](https://tex.z-dn.net/?f=3x%20%2B%20x%20%2B%20x%20%2B%2012%20%3D%2032)
Solving it further,
![5x + 12 = 32](https://tex.z-dn.net/?f=5x%20%2B%2012%20%3D%2032)
Subtracting 12 from both sides,
![5x + 12 - 12 = 32 - 12](https://tex.z-dn.net/?f=5x%20%2B%2012%20-%2012%20%3D%2032%20-%2012)
![5x = 20](https://tex.z-dn.net/?f=5x%20%3D%2020)
Dividing 5 from both sides,
![\frac{5x}{5} = \frac{20}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5x%7D%7B5%7D%20%20%3D%20%20%5Cfrac%7B20%7D%7B5%7D%20)
![x = 4](https://tex.z-dn.net/?f=x%20%3D%204)
Then,
- First side = 3x = 12 feet
- Second side = 4 feet
- Third side = x + 12 = 16 feet
And we are done with the answer !!

Do 35 times 19 and that is the whole square inches or so 35 squared times 19 squared
Answer:
15.733kg
Step-by-step explanation:
33.2 - 21.4 = 11.8
3/4 of the bucket empty is 11.8kg.
11.8 divided by 3 is 3.933. 3.933 x 4 is 15.733
Answer:
7y + 24
Step-by-step explanation:
Think of the negative sign to the left of the parentheses as being -1. Then apply the distributive property. The effect of a negative sign to the left of parentheses or a 1 to the left of parentheses is that each term inside the parentheses changes sign.
-(-7y - 24) = -1(-7y - 24) = (-1)(-7y) - (-1)(24) = 7y - (-24) = 7y + 24
