use the distributive property
combine alike terms
add the negative number to the other side
combine alike terms
then divide on both sides to get the variable by itself
Answer:
Step-by-step explanation:
2a + 6 / a² -9 = 2(a + 3) / (a² -3²)
= 2(a+3) / (a+3)(a-3) {a²-b² = (a+b)(a-b)
= 2 / (a-3)
The median is the middle number.
So if it’s, 5,6,7,8,11,11,15, then 8 is the median! Hope this helps!!
Im pretty sure the answer is p /2 - w =1 if this isnt the answer you can try a math site that explains all the rules to the problem
<span>Let the length of one side of the rectangle be x.
Then the opposite side of the rectangle also has a length of x.
The sum of the other two sides must be 17 - 2x.
So the length of one of these sides is 8.5 - x.
The length of two sides of the rectangle are x and 8.5 - x.
To find the area, we need to multiply these two values.
A(x) = (x) (8.5 - x) = 8.5x - x^2</span>
