PLS HELP Which of the following is a true statement regarding the quadratic formula form of the solutions to a quadratic equation?

The solutions x=4±85√2 must be left in exact form.

The solutions x=4±85√2 are in simplest form.

The solutions x=4±85√2 can be simplified to x=2±45√.

The solutions x=4±85√2 can be simplified to x=2±85√.

The solutions x=4±85√2 must be left in exact form.

Step-by-step explanation:

The quadratic formula -b ±√b^2- 4ac/2a will always give us solutions in the form; m±n√q, where m,n and q are integers.

These solutions must always be presented in its exact form, that is, with the square roots in it. Hence the solutions x=4±85√2 are in its exact form.

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
