  • L=2root6
  • B=root6

\\ \rm\Rrightarrow Perimeter=2(L+B)

\\ \rm\Rrightarrow Perimeter=2(2\sqrt{6}+\sqrt{6})

\\ \rm\Rrightarrow Perimeter=2(3\sqrt{6})

\\ \rm\Rrightarrow Perimeter=6\sqrt{6}

Answer:

6sqrt(6)

<em>BRAINLIEST, PLEASE!</em>

Step-by-step explanation:

2sqrt(6) x 2 = 4sqrt(6)

sqrt(6) x 2 = 2sqrt(6)

4sqrt(6) + 2sqrt(6) = 6sqrt(6)

What is the inverse of this function? f(x)=x−7
viva [34]

Answer:

<h3> f^−1(x) = x + 7</h3>

Step-by-step explanation:

Replace f(x) with y. y = x − 7

Interchange the variables.  x = y − 7

Solve for y.  y = x + 7

Solve for y and replace with f^−1 (x).  f^−1(x) = x + 7

I hope this helps have a great day :)

¿cuál es el vértice de una parábola que corta los ejes en los puntos (-1,0) , (5,0), (0,-10) ?​
kvasek [131]

Answer:

vertex: (2,-18)

Step-by-step explanation:

y = ax² + bx + c

(-1,0) : a - b + c = 0       ...(1)

(5,0) : 25a +5b +c = 0  ...(2)

(0,-10): 0a + 0b + c = -10        c=-10

(1) x5: 5a - 5b + 5c = 0  ...(3)

(2)+(3): 30a + 6c = 0          30a = -6c = 60        a = 2

(1): 2 - b -10 = 0     b = -8

Equation: y = 2x² - 8x -10 = 2 (x² -4x +4) - 18 = 2(x-2)² -18

equation: y = a(x-h)²+k     (h,k): vertex

vertex: (2,-18)
