</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.
2 + 3x = 4 + 2x + x^2
x^2 - x + 2 = 0
(x - 0.5)^2 - 0.25 + 2 = 0
(x - 0.5)^2 = -1.75
x - 0.5 = +/- sqrt 1.75 * i
x = 0.5 + 1.32i , 0.5 - 1.32i answer
Answer:Well, I don't know what you got so I can't tell you if it is right.
If it works in both equations, it depends of whether your equations are set up correctly.
Here is how I would do this problem.
Let x = no. of hot dogs,y = number of sodas.
First equation is just about the number of things.
x + y = 15
Second equation is about the cost of things.
1.5 x + .75 y = 18
solve x+y = 15 for y y = 15-x substitute into second equation
1.5x + .75(15 - x) = 18
You should get the correct answer for number of hot dogs if you solve this correctly. Put your answer in the x + y =15 equation to get y. Then put both x and y into the cost equation and check your answer.
Hope this helps.

Answer:
(1, -7)
Step-by-step explanation:
the difference between -4 & 6 is 10 so you add 5 (half) to -4 or subtract from 6, this gives you 1
you do the same for -9 and -5, the midpoint for those being -7, I hope this helps
