Step-by-step explanation:
have got a question which is as follow: Determine x,y,z∈R such that 2x2+y2+2z2−8x+2y−2xy+2xz−16z+35=0. This is a quite filthy looking equation
11)
8/20 = x/26
x = 26*8/20
x = 10.4
y/6 = 12/8
y = 12*6/8
y = 9
12)
x/8=12/15
x = 8*12/15
x = 6.4
10/y = 12/3
10/y = 4
y = 10/4
y = 2.5
Answer:
There are different kinds of shapes. The shapes have been sorted below:
- The shape that has one shape has four equal side lengths of three, and no right angles is rhombus.
- The opposite sides are parallel is parallelogram .
- Two shapes have two pairs of opposite equal side lengths is a parallelogram.
- A shape that has side lengths of four and eight is quadrilateral and octagon.
- Opposite sides are parallel, and there are no right angles is a parallelogram
- Heptagon has opposite equal side lengths of seven
- Quadrilaterals and triangle shape has shape has four equal side lengths of three and four right angles.
- Trapezoids has one set of opposite parallel sides and the shape that has one right angle is right-angled triangles.
- None of the side lengths in the last shape are equal is scalene triangle.

Answer:
C 12/48
Step-by-step explanation:
Original fraction:
x/y
The ratio of the numerator to the denominator is 1:4, so
x/y = 1/4
Cross multiply:
y = 4x
If three is added to the numerator and subtracted from the denominator, the new fraction reduces to one-third.
(x + 3)/(y - 3) = 1/3
Cross multiply:
3(x + 3) = 1(y - 3)
3x + 9 = y - 3
Above, we have y = 4x, so substitute 4x for y in the equation just above and solve for x.
3x + 9 = 4x - 3
12 = x
x = 12
y = 4(12) = 48
The original fraction is x/y = 12/48
