Answer:
(x - 3)² + (y + 9)² = 25
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
Given area = 25π , that is
πr² = 25π ( divide both sides by π )
r² = 25 ( take the square root of both sides )
r = 
= 5
With centre (h, k) = (3, - 9 ) and r = 5 , then
(x - 3)² + (y - (- 9) )² = 5² , that is
(x - 3)² + (y + 9)² = 25
70/50=35/25=7/5 is the equivalent fraction
Answer:
x= 3,-5
Step-by-step explanation:
(-x+9)(-x-9) - prefect square
(xy + x)(xy + x) - perfect square
(2x-3)(-3+2x) - not a perfect square
(16- x²)(x2 – 16) - not a perfect square
(4y? +25)(25+4y?) - not a perfect square
Answer:
It'd be a rational number
Step-by-step explanation:
<em>Real numbers are a set of numbers containing all of the rational numbers and all of the irrational numbers. </em>
Types of numbers <u>in the rational number "section" are decimals, whole, mixed, and fraction numbers whether they are negative or positive they are rational numbers.</u>
Irrational numbers are numbers that cannot be expressed as the ratio of two integers. So they would be square root, pi and more.
