The answer is x=-20.
6+ -28 -x =-2
You first add 28 to each side=6+-x=26 then you minus 6 from each side=-x=20.
Then you divide 20 by -x resulting in x=-20
Answer: 2/x+4x^2
Step-by-step explanation:
Do distrubitive property.
SO mutiply 2/5 to 5/x which is 10/5x or 2/x
then 2/5 times 10x^2
10*2/5=20/5 or 4
Done.
Have a nice day! :)
A triangular pyramid has 4 triangular faces. If all 4 have the same area, then one of them has area 1/4 of the surface area, 1836. That gives 459 sq ft as the area of one of the triangular faces.
I found the accompanying picture of this word problem.
The circle was inscribe in the triangle. The area outside of the circle but inside the triangle is the shaded area.
True. The shaded area of the following shape can be found by subtracting the area of the circle from the area of the triangle.
Answer:
The first should be (x+6, y-(-10).
The others, not sure but you have to plug them in.
