Answer:
x = -1/3
Step-by-step explanation:
4(3x-1)+8=2(3x+5)-8
Distribute
12x -4 +8 = 6x +10 -8
Combine like terms
12x +4 = 6x +2
Subtract 6x from each side
12x-6x +4 = 6x-6x +2
6x+4 =2
Subtract 4 from each side
6x+4-4=2-4
6x =-2
Divide each side by 6
6x/6 = -2/6
x = -1/3
V = 4/3(pi)(r^3)
V = 4/3(pi)(4.2^3)
V = 310 cm^3
Good luck!
Using an indirect proof:
Assume that the figure is a trapezoid.
All trapezoids are quadrilaterals.
All quadrilaterals' interior angles add up to 360° because any n-gon's interior angles add up to 180(n-2)°.
We are given that the trapezoid has three right angles.
All right angles are 90°, thus these right angles have a total measure of 270°.
We can conclude fourth angle must be 90°.
If it has four right angles, it is a rectangle.
Rectangles have two sets of parallel sides.
However, trapezoids have exactly one set of parallel sides.
Alas, our figure cannot be a trapezoid.
