A circle with a radius of 7cm. I know this is late lol. A square is equilateral so all sides are equal. To find the side lengths given the area you just need to take the square root of the area. You get 14cm. If you put a circle in the square the radius would just be half of one side.

GIVING BRAINLEST!!!Joe and Tim observed two points, P and Q, on a number line. A number line is shown from negative 1 to positiv
Veronika [31]

Answer:

Step-by-step explanation:

P is 5 ticks to the left of 0, so it would be -5/8

Q is 5 ticks to the right of 0, so it would be at 5/8

 an absolute value turns a negative number into a positive number

 so absolute value of  P located at -5/8 = 5/8

 this is the location of point Q

Joe said that the absolute values of the numbers represented by the two points are the same.

Solve the following quadratic function by using the quadratic formula: x^2 +<br> 2x - 1 = 2 *
elena55 [62]

Answer:

x = 1 or x = -3

Step-by-step explanation:

ax^{2} + bx + c = 0

x = \frac{-b±\sqrt{b^{2}-4ac } }{2a\\}

as x^{2} + 2x - 1 = 2 ⇔  x^{2} + 2x - 3 = 0, its solution is

x = \frac{-2±\sqrt{2^{2}-4 *1*(-3)} }{2*1}

=  \frac{-2±\sqrt{4+12} }{2} =  \frac{-2±\sqrt{16} }{2} =  \frac{-2±\ 4 }{2}

therefore, x = 1 or x = -3

hope this helps! :D

have a miraculous day, and brainliest is immensely appreciated!! <3
