C - 0.17c = 0.83c
When you write “c” at the start, or x or whatever, it has an understood (invisible) number 1. So you’re subtracting the decimal on the next variable from 1.
Normally, you would do whatever is inside of the parenthesees first then do the rest but we cant get any further so we remove the parenthasees by distrubtion
7a+6b-4(3a-3b)
-4(3a-3b)
a(b+c)=(ab)+(ac)
-4(3a-3b)=-12a-(-12b)
7a+6b-12a+12b
7a-12a+6b+12b
-5a+18b
that's the asnwer
The yellow one. the angles will always be the same no matter how small
They are using the point (2, 8) to write this equation. You know that because of the "y-8" in the equation, and also because it's bolded! lol. Anyways, what's missing is the slope and the x value from our point. The slope is -2. Find this by picking 2 points on the line and putting those into the slope equation. Use the bolded point and the x-intercept: (2,8) and (6,0):

. As stated earlier the x coordinate in the bolded point is 2. So our equation is y-8=-2(x-2). And there you Go!
Answer:

Step-by-step explanation:
The area of a regular octahedron is given by:
area =
. Let a is the length of the edge (diagonal).
area = 
Given that the diagonal of the octahedron is equal to height (h) of the tetrahedron i.e.
a = h, where h is the height of the tetrahedron and a is the diagonal of the octahedron. Let the edge of the tetrrahedron be e. To find the edge of the tetrahedron, we use:

The area of a tetrahedron is given by:
area =
=
The ratio of area of regular octahedron to area tetrahedron regular is given as:
Ratio =
