An Isosceles Triunde

Mathematics
2 answers:
Amanda [17]2 years ago
4 0

Answer:

base = x^4 - 3x^3+11x-4

Step-by-step explanation:

An isosceles triangle has 2 sides of equal length (a) and base (b)

⇒ perimeter of an isosceles = 2a + b

Given:

  • \textsf{leg (a)}=3x^4 - 6x-1  
  • \textsf{perimeter}=7x^4 - 3x^3-x-6

\implies \textsf{perimeter}=2a+b

\implies 7x^4 - 3x^3-x-6=2(3x^4 - 6x-1)+b

\implies 7x^4 - 3x^3-x-6=6x^4 - 12x-2+b

\implies x^4 - 3x^3+11x-4=b

Therefore, base = x^4 - 3x^3+11x-4

Answer:

Perimeter=sum of sides

  • Let base be y

\\ \tt\longmapsto 3x^4-6x-1+3x^4-6x-1+y=7x^4-3x^3-x-6

\\ \tt\longmapsto 6x^4-12x-2+y=7x^4-3x^3-x-6

\\ \tt\longmapsto y=x^4-3x^3+11x-4

Perform the indicated operation.(4r/r+3) - (5/r)
Aleks [24]

Answer:

4r² - 5r - 15 / r(r+3)

Step-by-step explanation:

To solve this problem, we will proceed the following way, writing down the common multiple of the denominators.

\frac{4r}{r+3} -\frac{5}{r} =\frac{4r(r)-5(r+3)}{r(r+3)} =\frac{4r^{2}-5r-15 }{r(r+3)}

Thus, the answer is 4r² - 5r - 15 / r(r+3)
