10. When you are trying to find the area you multiply two of the sides together. So assuming that the area is a square then it would be 10 inches on each side.
Answer:
Step-by-step explanation:
width = w
L = 5w - 6
w(5w - 6) = 18
5w^2 - 6w = 18
5w^2 - 6w - 18 = 0
Using the quadratic equation formula
x = 2.58997 and
x = -1.38997 This root cannot be. (No rectangle has a minus length.
w = 2.58997
L = 5*2.58997 - 6
L = 6.94985
w = 2.59
L = 6.95
The graphic you are looking for looks like the one shown in the attached figure.Remember that to graph a line you need two points, which you give them. The equation of the line you are looking for in this case will be given by y = 2x + 1
Answer:
a) The polynomial is equivalent to
, and the side length of the playground is
feet.
b) The perimeter of the playground, measured in feet, is
.
Step-by-step explanation:
a) By Geometry, we know that area of the square is equal to the square of the side length. If
is the area of the square, then must be a perfect square trinomial, that is:
(1)
Then, we must observe the following properties:
(2)

(3)

Therefore, the polynomial is equivalent to
, and the side length of the playground is
feet.
b) The perimeter of a square equals four times the side length. That is:

The perimeter of the playground, measured in feet, is
.
Answer:
B
Step-by-step explanation:
We need to find a answer that multiplies with 4 and 6 to 192.
4 x 6 x 9 doesn't equal 192 (It equals 216)
4 x 6 x 8 does equal 192
4 x 6 x 12 doesn't equal 192 (It equals 288)
4 x 6 x 48 doesn't equal 192 (It equals 1152)
