If you would like to find the equation, you can do this using the following steps:

D = b^2 - 4 * a * c
D = 12

0 = -x^2 + 8x + 2
D = 8^2 - 4 * (-1) * 2 = 64 + 8 = 72

0 = 2x^2 + 6x + 3
D = 6^2 - 4 * 2 * 3 = 36 - 24 = 12

0 = -x^2 + 4x + 1
D = 4^2 - 4 * (-1) * 1 = 16 + 4 = 20

0 = 4x^2 + 2x + 1
D = 2^2 - 4 * 4 * 1 = 4 - 16 = - 12

The correct result would be <span>0 = 2x^2 + 6x + 3.</span>

Which of the following statements must be true about this diagram? Check all that apply.
pishuonlain [190]

Answer:

Options (D), (E) and (F) are the correct options.

Step-by-step explanation:

From the figure attached,

1). Angle 4 is the exterior angle of the given triangle having interior angles 1, 2 and 3.

Therefore, by the property of exterior angle,

∠4 = ∠1 + ∠2

2). Since ∠4 = ∠1 + ∠2,

Therefore, ∠4 will be greater than ∠1

 Similarly, ∠4 will be greater than ∠2

Therefore, Options (D), (E) and (F) are the correct options.

KiRa [710]

Answer:

a). AB = 8 in

b). AB = 9.75 in

c). AC = 6.5 in

d). BC = 1.5 in

Step-by-step explanation:

a). Since, AB = AC + CB

   Length of AC = 5 in. and CB = 3 in.

   Therefore, AB = 5 + 3 = 8 in.

b). Given : AC = 6.25 in and CB = 3.5 in

   Therefore, AB = AC + CB = 6.25 + 3.5

   AB = 9.75 in.

c). Given: AB = 10.2 in. and BC = 3.7 in.

    AB = AC + BC

    AC = AB - BC

    AC = 10.2 - 3.7

    AC = 6.5 in

d). Given: AB = 4.75 in and AC = 3.25 in.

   BC = AB - AC

   BC = 4.75 - 3.25 = 1.5 in.
