I'm pretty sure it's:
A right rectangular prism with length 15 inches, width of 8 inches, and height of 6 inches.
A cross section parallel to the base is a rectangle measuring 15 inches by 8 inches
A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches
Just visualize the rectangle
Answer:
There's two answers.
-5, -4, and -3
3, 4, 5
Step-by-step explanation:
X=1/3 or x=-2
explanation:
Find factors of 3 and 2 which subtract to make 5.
We should realise that (3x2) - 1 = 5.
Find the cross products and subtract to get 5. Add in the signs. One of the factors must be 0.
The length is 5
Step-by-step explanation:
Let the length be x
Width = ( X - 2)
Area = 15
area = length * width
15 = x(x -2)
15 = x² - 2x
x² - 2x - 15 = 0
(x² + 3x) - (5x - 15) = 0
x(x + 3) - 5(x + 15) = 0
x - 5 = 0 or x + 15 = 0
x =5 or x = -15
x = 5
I filled it in for you, just remember that 200 is 2 times 100, aka 100%
