Step-by-step explanation:
<u>Step 1: Define</u>
[2 × (24 ÷ 3)] + 7
<u>Step 2: Evaluate</u>
- [Brackets] (Parenthesis) Divide: [2 × 8] + 7
- [Brackets] Multiply: 16 + 7
- Add: 23
To find the perimeter, you would add all the sides. Because we know the perimeter, we can represent this as an equation that needs solved.
362 = x + (2x) + (3x + 2), combine the like terms
362 = 6x + 2, subtract 2 from both sides
-2 -2
<u>360</u> = <u>6x</u>, divide both sides by 6
6 6
x = 60 feet
side 1 = 60 feet
side 2 = 120 feet
side 3 = 182 feet
check your work: 60 + 120 + 182 = 362 feet
Um... I think you mean decimal, fraction, and percentage, here it is:

Answer:
31
Step-by-step explanation:
a=(180-121)=59
c=(180-90)=90
