Absolute values are a way of finding a distant from zero, which means there will be 2 answers; one will be positive, and the other will be negative.
|<em>3x - 4</em>| = 5<em>and</em> |3<em>x - 4</em> = a^5 Because you need 2 answers, you have to make 5 positive and negative.
Another way to write this equation would be...
5=|3x-4|=—5
Now lets continue...
5=3x-4=—5
Add 4 to both sides...
9=3x=—1
Now divide by 3...
3=x= -1/3
So the solution is...
X={-1/3 3}
49
Because 7x7 is 49 & 4+9=13
Answer:
The volume of solids is measured in cubic measurements.
Step-by-step explanation:
Examples:
Volume of a cube: V = a^3
Volume of a sphere: 4/3 x pi x r^3
Volume of a triangle: 1/2 x b x h x l
For instance, a sphere with the radius of 5 feet:
4/3 x pi x 5^3 = V
V = 523.6 cubic feet
