Answer: There are five sides in a polygon.
Step-by-step explanation:
Since we have given that
Measure of exterior angles = 72°
We need to find the number of sides of polygon.
As we know the formula for "Number of sides of polygon".
Number of sides is given by
![\frac{360^\circ}{72^\circ}\\\\=5](https://tex.z-dn.net/?f=%5Cfrac%7B360%5E%5Ccirc%7D%7B72%5E%5Ccirc%7D%5C%5C%5C%5C%3D5)
Hence, there are five sides in a polygon.
Answer:
The first three options are the correct answers
Step-by-step-explanation:
1 × 24 = 24
2 × 12 = 24
3 × 8 = 24
Answer:
a) 72
Step-by-step explanation:
The rightmost digit, 5, is in the ones place, so its value is 5.
The next digit to the left, the 4 is in the sixes place, so its value is 4 * 6 = 24.
The next digit to the left, the 2, is in the 36 place, so its value is 2 * 36 = 72.
Answer: a) 72
Answer:
answer B is correct
Step-by-step explanation:
Hello,
this is not allowed to divide by 0 so we need to find the zeros of
![x^2+2x-15=0](https://tex.z-dn.net/?f=x%5E2%2B2x-15%3D0)
![x^2-3x+5x-15=0\\ x(x-3)+5(x-3)=0\\ (x+5)(x-3)=0\\ x=-5 \ \ or \ \ x=3](https://tex.z-dn.net/?f=%3C%3D%3E%20x%5E2-3x%2B5x-15%3D0%5C%5C%3C%3D%3E%20x%28x-3%29%2B5%28x-3%29%3D0%5C%5C%3C%3D%3E%20%28x%2B5%29%28x-3%29%3D0%5C%5C%3C%3D%3D%3E%20x%3D-5%20%5C%20%5C%20%20or%20%20%5C%20%5C%20x%3D3)
we need x different from -5 and from 3
answer B is correct
hope this helps
