Answer:
Width = 3/4 units or 0.75 units
perimeter of the rectangle = 23/2 = 11 1/2 units or 11.5 units
Step-by-step explanation:
A rectangle has two opposite sides equal in length. The 2 opposite sides are also parallel to each other.
The area of a rectangle = LW
where
L = length
W = width
The area of the rectangle = 3 3/4 units² = 15/4 units²
Length = 5 units
Therefore,
15/4 = 5W
multiply both sides by 4
15 = 20W
divide both sides by 20
W = 15/20
W = 3/4
Width = 3/4
Perimeter of the rectangle = 2L + 2W
Perimeter of the rectangle = 2(L + W)
Perimeter of the rectangle = 2(5 + 3/4)
perimeter of the rectangle = 2(23/4)
perimeter of the rectangle = 23/2 = 11 1/2 units or 11.5 units
Answer:
all that got a "-8" part
Step-by-step explanation:
for x=0 they are all at 0,-8
the y-intercept is at x=0 and can easily be calculated by replacing x with said 0, only the term "-8" remains
Answer:
either 1/3 chance or 1/6 chance

Answer:
Step-by-step explanation:
To simplify or to write in the form a+bi, you will need multiply the top and bottom by the bottom's conjugate like so:
Keep in mind when multiplying conjugates you only have to multiply first and last.
That is the product of (a+b) and (a-b) is (a+b)(a-b)=a^2-b^2.
(a+b) and (a-b) are conjugates
Let's multiply now:
i^2=-1
Answer:
A = 9x² + 48x + 65
Step-by-step explanation:
Area of a Square Formula: A = lw
Since a square's length is equal to its width, we simply plug it into the formula:
A = (3x + 8)(3x + 8)
Then we simply use FOIL to expand the distribution)
First - 3x(3x) = 9x²
Outside - 8(3x) = 24x
Inside - 8(3x) = 24x
Last - 8(8) = 64
Lastly, we combine like terms
9x² + 24x + 24x + 64
9x² + 48x + 64
