Answer:

16 km is the answer

Step-by-step explanation:

a (Colton to parents' house) = 12 km

b = ?

c (parents' house to grandparents' house) = 20 km

According to the Pythagoras theorem,

a² + b² = c²

12² + b² = 20²

144 + b² = 400

b² = 400 - 144

b² = 256

b = 16

∴ Colton is 16 km away from his grandparents' house.

(p-4)^2=4p complete the square if possible

Assoli18 [71]

Answer:

$p=6+2 \sqrt{5}, p=6-2 \sqrt{5}$

Step-by-step explanation:

Step 1: Given expression is $(p-4)^{2}=4 p$ .

Step 2: To write the equation in the quadratic form, subtract 4p from both sides of the equation.

$\Rightarrow(p-4)^{2}-4 p=4 p-4 p$

$\Rightarrow p^{2}-8 p+16-4 p=0$

$\Rightarrow p^{2}-12 p+16=0$

$\Rightarrow p^{2}-12 p=-16$

Step 3 :Add $\left(\frac{-12}{2}\right)^{2}$ on both sides of the equation.

$\Rightarrow p^{2}-12 p+\left(\frac{-12}{2}\right)^{2}=-16+\left(\frac{-12}{2}\right)^{2}$

$\Rightarrow p^{2}-12 p+36=-16+36$

$\Rightarrow(p-6)^{2}=20$

Step 4: Taking square root on both sides of the equation.

$(p-6)=\pm \sqrt{20}$

$p=6 \pm 2 \sqrt{5}$

Hence, $p=6+2 \sqrt{5}, p=6-2 \sqrt{5}$ .

Match each sequence below to statement that BEST fits it.

Aleksandr [31]

Answer: hello your question is poorly written attached below is the complete question

answer:

1 ) = I (

2) = F

3) = Z

4) = D

Step-by-step explanation:

attached below is the required solution.

1 ) = I ( The sequence diverges to infinity )

2) = F ( The sequence has a finite non-zero limit )

3) = Z ( The sequence converges to zero )

4) = D ( The sequence diverges )
