Wait for area, wouldn't you just times 13 and 5 and get 65 and then times 23?
<u>Answer:</u>
<u>Step-by-step explanation:</u>
- Perimeter: 2B + 2L
- => 2(3n - 7) + 2(n + 5)
- => 6n - 14 + 2n + 10
- => 8n - 4
<u>Conclusion:</u>
Therefore, the perimeter in terms of n is 8n - 4.
Hoped this helped.
since you know Lainey has 20 markers and the total cost is $6, all you have to do is solve 20/6 to find the cost of each marker. So, the answer would be about $2.33 dollars, since 20/6 would equal $2.333333333... and I just rounded it up. Hope I helped you! Good luck (:
Answer:
∠LPN = 57°
Step-by-step explanation:
arc LMN = 360° - 102° - 144° = 114°
∠LPN = 114°/2 = 57°
You are solving for the variable (c).
Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS (Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction)
First, subtract 8 from both sides
4c + 8 (-8) = 20 (-8)
4c = 20 - 8
4c = 12
Next, to fully isolate the variable (c), divide 4 from both sides
(4c)/4 = (12)/4
c = 12/4
c = 3
3 is your answer for c.
