Take the equation and distribute the 16 on the right:
64x - 16 = 16(4x - 1)
64x - 16 = 64x - 16
Since what is on both sides is identical, you'll always get a true statement no matter what value you pick for x.
This equation has infinitely many solutions.
This can be solved using the
angle bisector theorem. Note that line segment AD is the angle bisector of triangle DAB from angle DAB. Therefore, we know that the ratios
and
are equal. Solving, we get
. Cross multiplying, we get
, and solving this equation we get
.
10.2 is your answer.
Equilateral triangle<span> is a </span>triangle<span> in which all three sides are equal
</span>also 3 angles are equal and each angle = 60 degrees
so
2x - 4 = 60
2x = 64
x = 32
hope it helps
Answer:
B. 100π
Step-by-step explanation:
The surface area of a sphere is given by
SA = 4 pi r^2
The radius is 5
SA = 4 * pi * r^2
SA = 4 * pi * 25
SA = 100 pi
If there is no expression, it surely is equal to 0.
