BRAINLIEST PLEASE HELP np<br> If f(x)=-x^2+6x-1 and g(x)=3x^2-4x-1, find (f+g)(x)
raketka [301]

Answer:

\large\boxed{B.\ (f+g)(x)=2x^2+2x-2}

Step-by-step explanation:

f(x)=-x^2+6x-1\\\\g(x)=3x^2-4x-1\\\\(f+g)(x)=f(x)+g(x)\\\\\text{substitute:}\\\\(f+g)(x)=(-x^2+6x-1)+(3x^2-4x-1)\\\\(f+g)(x)=-x^2+6x-1+3x^2-4x-1\qquad\text{combine like terms}\\\\(f+g)(x)=(-x^2+3x^2)+(6x-4x)+(-1-1)\\\\(f+g)(x)=2x^2+2x-2

The three sides of a triangle are n, 3n+3, and 2n+11. If the perimeter of the triangle is 50 inches, what is the length of each
mylen [45]

Answer:

6, 21, and 23 inches

Step-by-step explanation:

The perimeter of a triangle is equal to the sum of all side lengths in that triangle. We're given the perimeter as 50 inches, and the side lengths as n, 3n + 3, and 2n + 11.

  • This means that we can algebraically solve the equation n + 3n + 3 + 2n + 11 = 50

Step 1: Combine like terms.

  • (n+3n+2n) + (3+11) = 50
  • 6n + 14 = 50

Step 2: Subtract 14 from both sides.

  • 6n + 14 - 14 = 50 - 14
  • 6n = 36

Step 3: Divide both sides by 6.

  • 6n/6 = 36/6
  • n = 6

Step 4: Plug in the value of n as 6 in each side.

  • (6) + (3(6) + 3) + (2(6)+11) = 50
  • (6) + (18+3) + (12+11) = 50
  • (6) + (21) + (23) = 50  

Therefore, the side lengths are 6, 21, and 23 inches.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
