Step-by-step explanation:
The answer being (93)=9! 3! 6! =9⋅8⋅73⋅2⋅1=84 possible arrangements.

</span>The square-shaped slice can be made from a slice parallel to the base of a right
rectangular prism, cube, and right rectangular pyramid with a square base. The triangle-shaped slice and isosceles
trapezoid-shaped slice can be made with a slice made perpendicular to the base
of a right rectangular pyramid. A
pentagon-shaped slice cannot be made from a slice made parallel or
perpendicular to the base of either a right rectangular prism, right
rectangular pyramid, or cube.
(2x² + 7x + 10) - (x² + 2x - 9) =
2x² + 7x + 10 - x² - 2x + 9 =
x² + 5x + 19
Answer:
B. x = 7, y = 4√2
Step-by-step explanation:
Drop a vertical from the upper left corner
This creates a rectangle and a 45-45-90 triangle
The bottom of the rectangle is 3
The legs of the triangle are 4
Therefor
x = 4 + 3
x = 7
For a 45-45-90 triangle
the hypotenuse = leg * √2
y = 4√2
Answer:
Choice 3
Step-by-step explanation:
add 63 and 64 which gives you 127. Then you subtract 180 and 127. This gives you 53. 63+53+64=180. Know that the angle is 180 degrees too so you don't even have to do math.
