Answer:

108 ft

Step-by-step explanation:

The total length in inches of the perimeter of the model is ...

7 in + 3 in + 3 in + 5 in = 18 in

The total length of the walkway will have the same ratio to this perimeter that the corresponding sides have:

EF/AB = 42 ft/(7 in) = (walkway length)/(18 in)

Multiplying by 18 in, we get ...

walkway length = (42 ft)(18 in)/(7 in)

walkway length = 108 ft

-7(n - 2) + 2n = -5(n + 6)

skad [1K]

Given the expression below

$-7(n-2)+2n=-5(n+6)$

To find n

Open the brackets

$\begin{gathered} -7(n-2)+2n=-5(n+6) \\ -7n+14+2n=-5n-30 \\ -7n+2n+14=-5n-30 \\ -5n+14=-5n-30 \end{gathered}$

Collect like terms

$\begin{gathered} -5n+14=-5n-30 \\ -5n-(-5n)=-30-14 \\ 0\ne-44 \end{gathered}$

Since, the sides are not equal,

Hence, there is no solution

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

= sqrt ( 36+16)

=sqrt (52) = 7.2

angle = tan^-1(6/4) = 56 degrees
