A piece of cloth is folded into a square with a side length measuring x inches. When it is unfolded, it has an area of x2 + 27x + 162 square inches.Which could be the dimensions of the rectangular piece of cloth when it is unfolded? Remember, the area of a rectangle can be determined using the formula A = lw.
length = (x + 9) inches and width = (x + 3) inches
length = (x − 3) inches and width = (x − 9) inches
length = (x + 18) inches and width = (x + 9) inches
length = (x − 9) inches and width = (x − 18) inches
Answers
we have
Using a graph tool------> to resolve the second order equation
the solution is
so
therefore
the answer is the option
length = (x + 18) inches and width = (x + 9) inches
(x+9)(x+3=x²+21+27 No
(x-3)(x-9)=x²-12x+27 No
(x+18)(x+9)=x²+27x+162 Yes
(x-9)(x-18)=x²-27x+162 No
Answer C

the equation of a line is:
y = mx + c
To find c, plug in the given
y = 4
x = 7
m = -4
4 = -4(7) + c
4 = - 28 + c
take -28 to the other side
4 = -28 + c
+28 +28

The length of the legs of a right triangle in which one acute angle measures 19° and the hypotenuse is 15 units are 4.9 units and 14.2 units.
What is a right angle triangle?
A right angle triangle has one of its angles as 90 degrees. The sides can be found using pythagoras theorem or trigonometric ratios.
Therefore,
sin 19 = opposite / hypotenuse
sin 19 = h / 15
cross multiply
h = 15 sin 19
h = 4.88352231686 = 4.9 units
Hence,
cos 19 = adjacent / hypotenuse
cos 19 = x / 15
cross multiply
x = 15 cos 19
x = 14.182778634 = 14.2 units
Therefore, the other legs are 4.9 units and 14.2 units.

The area of a regular hexagon with an apothem 10.4 yards long and a side 12 yards longis 374.4 yard^2.
What is a regular hexagon?
A regular hexagon is defined as a closed shape consisting of six equal sides and six equal angles. The sum of the measure of angles of a regular hexagon is 120 degrees.
The area of a regular hexagon =
It is given that apothem is 10.4 yards and side is 12 yards long.
The area of a regular hexagon =
= 6× 10.4 × (12/2)
= 374.4 yard^2
Thus the area of a regular hexagon is 374.4 yard^2.

So the area, A, of the regular hexagon is 6 x the area of one triangle
The area of a triangle is half the base times the height
The height of a triangle is the apothem of the hexagon and the base is the side of the hexagon.
A = 6* 10.4 * (12/2) yard^2 = 374.4 yard^2
