Answer:
Step-by-step explanation:
Distance Formula:
Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>:
X^2−9=0
Add 9 to both sides.
x^2−9+9=0+9
x^2=9
Take square root.
x=±√9
x=3 or x=−3
Answer:
x=3 or x=−3
The answer is 1/2.
Only whole numbers can be integers for future reference :)
The real square root is .09
You know that the sides of a square are increased by 2 inches: the expression should be written as (x+2)
The area is 25 square inches
The area of a square is s×s or s²
so it can be solved as:
(x+2)²=25
x+2=5
x=3
<u>The length of the original side is 3 inches</u>
Hope it helps!
