Answer:

Width = 160

Length = 110

Step-by-step explanation:

Perimeter is the sum of all the sides

They tell you that the length is 50 m shorter than the width

so L = W - 50

W = W

540 = W + W + W-50 + W-50

540 = 2W + 2(W-50)

540 = 2W + 2W - 100

540 = 4W - 100

640 = 4W

W = 160

L = 160 - 50

L = 110

Answer:

Length: 110 m

Width: 160 m

Step-by-step explanation:

The formula for perimeter of a rectangle is P = 2L + 2W.

We can write the length in terms of width if width is w:

Length: w - 50

Width: w

Plug the values into the formula.

540 = 2(w - 50) + 2w

540 = 2w - 100 + 2w

540 = 4w - 100

640 = 4w

w = 160

find length by subtracting 50 from the width

160-50=110

Therefore, the length is 110 and the width is 160.

HELP ME !!!!!!<br> instruction given the quadrilateral ABCD inscribed in the circle, find x and y

grin007 [14]

The opposite angles in a cyclic quadrilateral are supplementary. i.e., the sum of the opposite angles is equal to 180˚

So using theorem we find that

∠A+∠C = 180

x + 108 = 180

x = 180 - 108

x = 72

∠B+∠D = 180

88 + y = 180

y = 180 - 88

y = 92

If (x+1)(x-3)=12, then which of the following statements is true?

Semmy [17]

Answer:

C. x-5=0 or x+3=0

Step-by-step explanation:

Given,

$(x+1)(x-3)=12$

$x^2+1x-3x-3=12$ ( By multiplication )

$x^2-2x-3=12$ ( By operating like terms )

$x^2-2x-3-12=0$ ( Subtracting 12 on both sides )

$x^2-2x-15=0$

$x^2-5x+3x-15=0$ ( By middle term splitting )

$x(x-5)+3(x-5)=0$

$(x+3)(x-5)=0$

By the zero product property,

$(x+3)=0\text{ or }(x-5) =0$

Hence, option C is correct.
