It's 8% because if you write out .4 of 4.9=___, that equals to .4/4.9=x/100 which is basically .5/5=x/100. Then, since 5x20=100, that means .5x20=x. You would get 8.
Answer:
-6/9 = -2/3 (C)
Step-by-step explanation:
Answer:
±1, ±2, and ±4
Step-by-step explanation:
4x² + bx + c = (Ax + B) (Cx + D)
Distribute:
4x² + bx + c = ACx² + (AD + BC) x + BD
Matching the coefficients, AC = 4. So A must be a factor of 4. Possible values of A are therefore ±1, ±2, and ±4.
A polygon that has both reflectional and rotational symmetry includes:
- B. Square
- C. Triangle
- E. Equilateral Triangle.
<h3>What is a polygon?</h3>
A polygon is a closed curve made up of a set of line segments (sides) connected in such a way that no two segments cross.
Examples of polygons are triangles (three sides), quadrilaterals (four sides), and pentagons (five sides).
Triangle, square, and other quadrilaterals have both line symmetry and rotational symmetry.
Thus, a polygon that has both reflectional and rotational symmetry includes Options B, C, and E.
