I believe the answer is 20+2x squared.
Just ask if you want it to be clarified better
Answer:
15.73
Step-by-step explanation:
Straight angle is 180 degrees. So the given angles add up to 180.
(6x - 3) + (5x + 10) = 180
11x + 7 = 180
-7 -7
11x = 173
Answer:
Option B: 3x(x - 3)(x - 5)
Step-by-step explanation:
The given polynomial is: 3x³ - 24x² + 45x
To factorize it: 3x³ - 24x² + 45x
Since, 3x is common through out we can take it out.
⇒ 3x(x² - 8x + 15)
Now we have to factorize (x² - 8x + 15)
The roots of this quadratic equation is: 5, 3.
Therefore, x² - 8x + 15 = (x - 3)(x - 5)
Combining them, the factors of the polynomial would be:
(B) 3x(x - 3)(x - 5)
Answer:
7.14
Step-by-step explanation:
Answa line of symmetry will connect a vertex and a midpoint of an opposite side
it has 7-fold symmetry.
Step-by-step explanation:
A line of symmetry is a line that we can use to "fold" a figure in half. In order to do this, we will "fold" the figure from a vertex to the middle of the side opposite the vertex. Since there are 7 vertices, there will be 7 lines of reflection. i looked it up so i hope this helps you can thank
