DaniilM [7]

Answer:

<em>The</em><em> </em><em>required</em><em> </em><em>equation</em><em> </em><em>is</em><em> </em><em>5x-y-51</em><em> </em><em>=</em><em> </em><em>0</em>

Step-by-step explanation:

$the \: given \: equation \: is \\ y = 5x + 1 \\ 5x - y + 1 = 0 \\ the \: equation \: of \: the \: line \: \\ parallel \: to \: 5x - y + 1 = 0 \: \: is \\ 5x - y + k = 0 \\ since \: it \: passes \: through \: (10, - 1) \\ 5(10) - ( - 1) + k = 0 \\ 50 + 1 + k = 0 \\k = - 51 \\ the \: equation \: of \: the \: line \: parallel \: t o\: \\ 5x - y + 1 = 0 \: \: \: is \\ \: 5x - y - 51 = 0$

A square has an area of 64 cm<br> Find the perimeter of the square.

julia-pushkina [17]

Answer:32cm

Step-by-step explanation:

Length=L

Area=64

Area=L x L

64=L^2

L^2=64

Take them square root of both sides

√(L^2)=√(64)

L=8

Perimeter of square=4 x L

Perimeter of square=4 x 8

Perimeter of square=32

Perimeter =32cm
