Answer: 16x - 30

Step-by-step explanation:

Determine values of L and W

We know that the perimeter can be found by the equation p = 2L + 2W where L is the length and W is the width

L = 3x-4

W = 5x-11

Plug in the values of L and W into the equation and solve

p = 2L + 2W

p = 2(3x - 4) + 2(5x - 11)

p = 6x - 8 + 10x - 22

p = 16x - 30

Answer:

(16x - 30) units

Step-by-step explanation:

Perimeter = 2[length + width]

= 2[3x-4 + 5x-11]

= 2[8x - 15]

= 16x - 30

For the function F defined by F(x) = x2 – 2x + 4, find F(b+3).
Ivanshal [37]

Answer:

\displaystyle F(b + 3) = b^2 + 4b + 7

Step-by-step explanation:

We are given the function:

\displaystlye F(x) = x^2 - 2x + 4

And we want to find F(<em>b</em> + 3).

We can substitute:

\displaystyle F(b + 3) = (b + 3)^2 - 2(b+3) + 4

Expand:

\displaystyle = (b^2 + 6b + 9) + (-2b -6) + 4

Rearrange:

\displaystyle = (b^2) + (6b-2b) + (9 - 6 + 4)

Combine like terms. Hence:

\displaystyle = b^2 +4b + 7

In conclusion:

\displaystyle F(b + 3) = b^2 + 4b + 7
