-2|3x+2| = -12
|3x+2| = 6
3x + 2 = 6
3x + 4
x = 4/3
|3x+2| = -6
3x +2 = -6
3x = -8
x = -8/3
So we have the answers being 4/3 and -8/3
Answer:
Step-by-step explanation:
Given
The length of a cuboid is
breadth is
Total surface area is
Surface area is given by
Insert the values
Draw out a number line. Make sure -28 is on the number line, along with other optional values (such as 0 perhaps). At -28, plot an open circle or hole. This indicates this value is not part of the solution set. This is because there is no "or equal to" as part of the inequality sign. Then shade to the left to indicate values smaller than -28.
So in summary, you'll have an open hole at -28 and shading to the left.
Answer:
[0,11]
Step-by-step explanation:
Required
Represent Set of numbers from 0 to 11
<em>In interval notation; the square bracket [ ... ] implies that the number in question is inclusive of the set.</em>
So; Given that
Beginning = 0
End = 11
The interval notation can be represented as [0,11] because both numbers are inclusive of the set.
Answer:
<em>128</em>
Step-by-step explanation:
<em>Method A.</em>
The volume of the prism is 2 cubic units.
Each cube has side length of 1/4 unit.
The volume of each cube is (1/4)^3 cubic unit.
The volume of each cube is 1/64 cubic unit.
To find the number of cubes that fit in the prism, we divide the volume of the prism by the volume of one cube.
(2 cubic units)/(1/64 cubic units) =
= 2/(1/64)
= 2 * 64
= 128
<em>Method B.</em>
Imagine that the prism has side lengths 1 unit, 1 unit, and 2 units (which does result in a 2 cubic unit volume.) Since each cube has side length 1/4 unit, then you can fit 4 cubes by 4 cubes by 8 cubes in the prism. Then the number of cubes is: 4 * 4 * 8 = 128
