What is the center and radius of the circle with equation (x + 4)2 + (x + 1)2 = 49? Graph the circle.

center: (-4, -1)

radius: 7

Step-by-step explanation:

The standard equation of a circle is represented by the formula:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center and r is the radius. From the equation we have, we can say that

h = -4

k = -1

r = √49 = 7

So, the center is (-4, -1) and the radius is 7.

Here is a vague graph of what this equation may look like:

have a great day!!

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
