Answer:
x = 10
Explanation:
A square is a quadrilateral in which all sides are equal.
We are given that:
ABCD is a square
AB = 5x - 10
BC = 2x + 20
Since we're talking about a square, therefore:
AB = BC
5x - 10 = 2x + 20
5x - 2x = 20 + 10
3x = 30
x = 30/3
x = 10
Now, we can check our solution:
AB = 5(10) - 10 = 40 units
BC = 2(10) + 20 = 40 units
We can see that both sides are equal
Hope this helps :)
Answer:
30
Step-by-step explanation:
Each exterior angle is 180 -168 = 12 degrees. The sum of them is 360, so there are ...
360/12 = 30
exterior angles, hence 30 sides to the polygon.
Answer: -1, 0, 1, 2, 3
Step-by-step explanation:
If we say the expression out loud, we say it as "m is greater than -2 but less than or equal to 3."
This is because < or > means less than or greater than. These don't include the given value.
≤ or ≥ means less than or equal to or greater than or equal to. These do include the given value/values.
In this equation, we don't include -2, but we include 3. That's why the included values are -1, 0, 1, 2, 3.
