fomenos

Answer:

d

Step-by-step explanation:

x 1=  \frac{ - b +  \sqrt{ {b}^{2}  - 4ac} }{2a}  \\ x2 =  \frac{ - b  -   \sqrt{ {b}^{2} -  4ac} }{2a}  \\ x1 =  \frac{ - 2 +  \sqrt{ {2}^{2}  - 4\times 1 \times ( - 3)} }{2}  = 1 \\ x2 =   \frac{ - 2 -  \sqrt{ {2}^{2}  - 4 \times 1 \times ( - 3)} }{2}  =  - 3

PLLLZZ HELP!!!!
topjm [15]

Answer:

3. A quadrilateral with each side length 4 cm

Step-by-step explanation:

We need to understand what is a unique polygon?

<em>It means all regular polygons with the same number of sides are similar.</em>

1.A triangle with angles 30 degrees, 60 degrees, and 90 degrees

It is an right triangle, so the 3 sides are not simillar, so it is wrong

2. A triangle with side lengths 5 cm, 4 cm, and 3 cm

It is a triangle with the 3 sides are not simillar, so it is wrong

3. A quadrilateral with each side length 4 cm

It is an square with the 4 sides are simillar, so it is true

4. A triangle with side lengths 7 cm and 8 cm and a 40-degree angle

It is a triangle with the 3 sides are not simillar, so it is wrong

Hence, we choose 3.

Solve system by using substitution: 5x + 3y = -4 <br> y - 2x = 6
horrorfan [7]

Answer:

x = -11/3, y = -4/3

Step-by-step explanation:

y-2x=6\\y = 2x + 6

3(2x + 6) = -4\\6x + 18 = -4\\6x = -22\\x = -11/3

3y = -4\\y = -4/3
