Answer:

Step-by-step explanation:

1) It's done by making use of one postulate, a theorem whose proof is evident. There is one among many, in Euclidean Geometry, about this particular case.

2)According to Plane Intersection Postulate. If two planes intersect each other, then their intersection is a line. If Plane STL and Plane Z would intersect, they would at line XL, not a line segment.

The radius of a circle is 4 yards. What is its circumference?

Setler [38]

Answer:

See answer below

Step-by-step explanation:

Hi there,

To get started, recall the circumference formula.

$C = \pi r^{2}$ where π is the irrational number 3.14159... and r is the radius of the circle. Circumference is like perimeter but for a circle; it is the distance around the boundary.

$C = \pi (4 \ yd)^{2}= 16\pi \ yd^{2} = 50.27 \ yd^{2}$ (approximately)

thanks,

-x+4(x+3)=9 substitution method

Rudiy27

-x+4(x+3) = 9

Multiplying...

-x+4x+12=9
So,
3x + 12 = 9

Now, subtract 12 from both sides.

3x + 12 - 12 = 9 - 12
3x = -3

Then, divide by 3.
3x/3 = -3/3
x = -1
