Answer:

x = 6

y = -6

Step-by-step explanation:

By adding both equations :-

=》-4x -2y + 4x + 8y = -12 + (-24)

=》-4x + 4x + 8y - 2y = -12 - 24

=》6y = -36

=》y = -36 ÷ 6

=》y = -6

putting the value of y in equation 2

=》4x + 8y = -24

=》4x + (8 × -6) = -24

=》4x - 48= -24

=》4x = 48 - 24

=》x = 24 / 4

=》x = 6

The area of a square room is 16x^2+72x+81. what is the length of one side of the room

maxonik [38]

To find this you know that the A of a square = s^2

So the length of one side equals $s = \sqrt{16 x^{2} +72x+81}$

Since this is a perfect square, it would equal $A = (4x+9)^{2}$

And $s = \sqrt{(4x+9)^{2}} = 4x+9$

Also you know it is a perfect square because the first and last terms are perfect squares :) :D
