Answer: Associative property
Step-by-step explanation: it is the same equation but they switched the numbers around on the other side of the equal sign so therefore its associative property
Answer: First option is correct.
Step-by-step explanation:
Since we have given that
PA = 22
PB = 22+40=62
PC = 26
PD = 26+d
As we know the rule of tangents :
PA.PB=PC.PD

Hence, First option is correct.
Answer: <em>x</em>
Step-by-step explanation:
For this equation, the variable <em>y</em> is dependent on the value of<em> x</em>. The value of <em>y</em> changes depending on the value of<em> x</em>. This means that <em>x</em> is the independent variable for this equation.
