Answer:
The length of side of original square is: 20 inches
Step-by-step explanation:
Let x be the length of side of original square
Then x+5 will be the side of new square
Th formula for perimeter is:
As we know the perimeter of the new square we can use the perimeter to find the value of x
The value of x is 20 inches.
Hence,
The length of side of original square is: 20 inches

Step-by-step explanation:
We know that
the equation of the circle with center (0, 0) is ---------> x²+y²=r²
Step 1
find the radius
<span>the radius is simply the distance from the center to the point (5,2)
</span>d=√[(5²+2²)]-------> d=√29
r=√29
the equation of the circle is
x²+y²=29
the answer is x²+y²=29
Answer: x=13
Step-by-step explanation:
(x-5) + x = 21 given
2x-5=21 combined like terms
2x=26 addition property of equality
x=13 division property of equality
