Answer:

d. Two complex solutions

Step-by-step explanation:

We have been given a trinomial $2x^2+4x+4$ and we are supposed to predict the type of solutions of our given trinomial.

We will use discriminant formula to solve for our given problem.

$\text{Discriminant}=b^2-4ac$ , where,

$a =\text{Coefficient of }x^2$ ,

$b =\text{Coefficient of }x$ ,

$c =\text{Constant }$

Conclusion from the result of Discriminant are:

$D$

$D=0\text{ means one real zero with of multiplicity two}$

$D>0\text{ means two distinct zeroes}$

Upon substituting our given values in above formula we will get,

$\text{Discriminant}=4^2-4*2*4$

$\text{Discriminant}=16-32$

$\text{Discriminant}=-16$

Since our discriminant is less than zero, therefore, out given trinomial will have two complex solutions and option d is the correct choice.

I need help with this question ASAP!!!!!!!!!!!!!

The height of the flag pole is 51 ft.

Solution:

Paul creates the smaller triangle and flag pole creates the larger triangle.

Base of smaller triangle = 10 ft

Height of smaller triangle = 6 ft

Base of the larger triangle = 85 ft

Let the height of the flagpole be h.

$$\Rightarrow \frac{6}{10} =\frac{h}{85}$

Multiply by 85 on both sides.

$$\Rightarrow 85 \times \frac{6}{10} =\frac{h}{85} \times85$

$$\Rightarrow \frac{510}{10} =h$

⇒ 51 = h

The height of the flag pole is 51 ft.
