What I do not understand what you are asking, can you repeat it pls.
Step-by-step explanation:
Answer: Quadrilateral
Explanation:
Any four sided polygon is considered a quadrilateral since "quad" means "four". You can think of a quad bike, which has four wheels, to help remember this math term.
Usually in problems like this, we'll be given information about if certain sides are parallel or the same length. However, we don't this info, so we cannot narrow down this classification anymore.
The perimeter of the shape is 94 cm and the area is 462 sq cm.
Step-by-step explanation:
Given,
The radius (r) = 14 cm
To find the area and perimeter of the given shape.
The given shape is
of the full circle.
Formula
The perimeter of the circle = 2πr
The perimeter of the given shape =
(2πr)+r+r =
(2πr)+2r
The area of the circle = πr²
Now,
The perimeter of the given shape =
(2×
×14)+2×14 = 94 cm
The area of the given shape =
(πr²)
=
×
×14² = 462 sq cm
Give the number a label. That can be anything you want. A lot of people will use 'x' every single time they do a math problem,but there's no reason to do that and it's boring. Let's call our number ' M ' for 'Mystery number'. OK ?
The number . . . M
The square of the number . . . M²
Two more than the square of the number . . . M² + 2
You said that this is equal to 123, so we can write <u> M² + 2 = 123</u>
That's the equation we have to take and solve for ' M '.
Subtract 2 from each side of the equation, and you have M² = 121 .
Take the square root of each side: M = √121 .
The Mystery number is the square root of 121.
If you don't happen to know what that is, then you can use your pocket
calculator, or the calculator that comes with your computer (if you know
how to find it). They will all tell you that the square root of 121 is <em>11</em> .
That's a fine and wonderful answer, but technically, it's only half of the
answer. Any equation that has something squared in it almost always
has two solutions, and this one does.
The square root of 121 is a number that gives you 121 when you
multiply it by itself. ' 11 ' does that: (11 x 11) = 121 . Is there <em><u>another</u></em>
number that does the same thing ?
How about ' -11 ' ? Look at this: ( -11 x -11 ) = 121 . (Remember that
if both numbers being multiplied have the <em>same sign</em>, then their product
is positive.)
The bottom line is: The mystery number is<em> +11</em> and also<em> -11</em> .
Either one does what you want . . . When you square it and then
add 2 more, you get 123 either way.
Answer:
2. 6/9
3.2/4
4. 8/10
Step-by-step explanation:
basically the idea is to find something in the same fact family so like the example on 1, follow that and try to answer the next problams on your own its really easy
( sorry if im wrong or not i tried to help)
