What makes a square a square <br> why isn't a rectangle?
Lilit [14]
A square is a geometrical figure that has 4 congruent sides and angles. This means all side lengths and angles are the same.

A rectangle is a geometrical figure that has 4 similar sides but are not the same length. However, a rectangle does have congruent angles. A rectangle has 2 sides that are double the other 2 sides, in which both of each (length & width) have the same measurement.

I hope this helps!

Find the area of the following circles. a. A circle with a 8-inch radius b. A circle with a 10-kilometer radius c. A circle with
Thepotemich [5.8K]
Area of a circle is A= \pi r^2.  The first one, a, the radius squared is 8*8=64.  So A=64 \pi.  If you multiply in pi as 3.14, you'll have 200.96 square inches.  The second one, b, the radius squared is 10*10=100.  So A=100 \pi square kilometers.  If you multiply in pi as 3.14 you'll have 314 square kilometers.  The third one, c, the radius squared is 14*14=196.  So A=196 \pi yd^2.  Or you could multiply in pi as 3.14 to get 615.44 yd squared.  For the last one, d, the radius squared is 22*22=484 cm.  Therefore, A=484 \pi cm^2, or multiply in 3.14 for pi to get 1519.76 cm squared.  There you go!

Help me plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz tired
LenKa [72]

So, y-intercept is (0,3) and x-intercept is (3/7,0)

Step-by-step explanation:

We are given:

y=-7x+3

We need to find y-intercept and x-intercept

Finding y-intercept

To find y-intercept we put x =0

Solving:

y=-7x+3\\y=-7(0)+3\\y=3

So, y-intercept is (0,3)

Finding x-intercept

To find x-intercept we put y =0

Solving:

y=-7x+3\\0=-7x+3\\-7x=-3\\x=-3/-7\\x=3/7

So, x-intercept is (3/7,0)

So, y-intercept is (0,3) and x-intercept is (3/7,0)
