3a =18
3a/3 = 18/3
a = 18/3
a = 6
Hope this helps
Answer:
A. <em>A </em>and <em>F</em>.
Step-by-step explanation:
By observing the number line given, you can assume that in between -4 and -6 would be the number -5, replaced by the variable <em>A</em>, and the same thing with 4 and 6, where 5 is replaced by <em>F</em>.
Using order of operations, we can see we should first solve for the exponents, and then multiply the exponent values by each other.
3²×
9×243
2187
Another way to solve this is to add the exponents together and simply do
. We can only do that in this case, however, because the values are being multiplied by each other.
Either way we solve, we will get
2187 as our final answer.
A line and a point can be collinear” is correct about a line and a point.
In geometry a line:
<span>
• is straight (no curves),
• has no thickness, and
• extends in both directions without end (infinitely). </span>
In modern mathematics, a point refers usually to an element of some set called a space. More specifically, in Euclidean geometry, a point<span> is a primitive notion upon which the geometry is built.</span>
