Answer:
n = 7/2
Step-by-step explanation:
4n^2-22=27
4n^2 = 27 + 22
4n^2/4 = 49/4
sqrtn^2 = sqrt(49/4)
n = 7/2
A 15% percent markup means that the typewriter cost was increased by 15%, or 0.15 by moving the decimal 2 places to the left. If the original price was x, and 15% of it is 0.15*x, we can add them up to get 1.15*x=129.95. Dividing both sides by 1.15, we get x=113 dollars
Answer:
3(x + 9)(x + 9)
Step-by-step explanation:
- 3x^2 + 54x + 243
- 3(x^2 + 18x + 81)
a + b = 18
a + b = 81
a= = 9, b = 9
3. 3(x + 9)(x + 9)
