A <span> regular </span>icosahedron<span> is a 3D convex polyhedron with 20 faces, 30 edges and 12 vertices while a regular octahedron has 8 faces. A tetrahedron has 4 faces and is shaped like a pyramid. All of these have triangular bases. A regular hexahedron has six faces and a base of a square</span>
Well, if 24 is 4% of a number, then you need to work out what 100% is.
The formula is 100/4 i.e. 100% divided by 4%= 25
25 x 24 = 600
<span><u><em>The correct answers are: </em></u>
1) A;
2) A;
4) D
3 cannot be done because the graph is not shown.
<u><em>Explanation:</em></u><span><u><em> </em></u>
1) Shifting a graph to the left, we would normally think of subtracting 1 from the function. However, horizontal translations are the opposite; left means adding 1 to x, while right means subtracting 1 from x.
2) A reflection in the x-axis means the y-coordinate will be negated (the opposite sign). This means that g(x)=-f(x)=-(x^2+5=-x^2-5.
4) To perform a vertical stretch of a function, we multiply by the factor; this gives us y=6x.</span></span>
When you are trying to find the side lengths you can use the law of sines. The law of sines goes like this: (Sin A (angle a))/A (side length) =(Sin B (angle b))/B (side length)

Answer:
A). 15
B). -1.2
Step-by-step explanation:
A). [10(x+3)]-20 = 160
10x+30-20 = 160
10x+10 = 160
10x = 160-10
10x = 150
x = 150/10
x = 15
B). 5{[4(8+(5x))]-9} = 85
5(32+20x+9) = 85
5(32+9+20x) = 85
5(41+20x) = 85
205+100x = 85
100x = 85-205
100x = -120
100x/100 = -120/100
x = -1.2
