Answer:

p = 2 or p = -15 the answer is A.

Step-by-step explanation:

Solve for p:

p^2 + 13 p - 30 = 0

The left hand side factors into a product with two terms:

(p - 2) (p + 15) = 0

Split into two equations:

p - 2 = 0 or p + 15 = 0

Add 2 to both sides:

p = 2 or p + 15 = 0

Subtract 15 from both sides:

Answer: p = 2 or p = -15

What is the length of AB

Anettt [7]

Answer:

$\boxed{\boxed{\overline{AB}=16}}$

Step-by-step explanation:

In the triangle ABC, m∠ABC=90°. Hence, it is right angle triangle.

$\tan \theta=\dfrac{p}{b}=\dfrac{AB}{64}$ --------1

In the triangle ABD, m∠ABD=90°. Hence, it is right angle triangle.

$\cot (90-\theta)=\dfrac{b}{p}=\dfrac{4}{AB}$

As $\cot (90-\theta)=\tan \theta$ , so

$\tan \theta=\dfrac{b}{p}=\dfrac{4}{AB}$ ---------2

From equation 1 and 2,

$\Rightarrow \dfrac{AB}{64}=\dfrac{4}{AB}$

$\Rightarrow AB^2=64\times 4$

$\Rightarrow AB^2=256$

$\Rightarrow AB=\sqrt{256}$

$\Rightarrow AB=16$
