Answer:
-4/3
Step-by-step explanation:
- -14 -8 = -2 (-3x + 7)
- -22= 6x-14
- 6x=14-22
- 6x=-8
- x= -8/6
- x= -4/3
Recall that the area of an equilateral triangle with side length is .
In the plane, the base is given by two equations:
so that for any given , the vertical distance between the two sides of the circle is
and this is the side of length of each triangular cross-section for each . Then the area of each cross-section is
and the volume of the solid is
Answer: E. 282.3
The unit rate for the most recent years (2001&2003) is 5.3. Multiply that by the number of years there was until 2015 and add it to 218.7 to get 282.3.
You would have to multiply by the reciprocal so 68 times 4 is 272. Therefore, one forth of 272 is 68. <span />
Answer:
9 x 6 = 54, 54 divided by 2 = 27
27 x 4 = 108
Just find the area of one triangle then multiply by 4 since there 4 triangles.
