Answer:

a = 5

Step-by-step explanation:

a^2 + b^2 = c^2

Substitute

b = 12

c = 13

a^2 + 12^2 = 13^2

a^2 + 144 = 169

a^2 = 25

a = \sqrt{25} \\

a = 5

What are the values that make x^2 + bx + 64 a perfect square?
spayn [35]

Answer:

b = ±16

Step-by-step explanation:

Normally to find the number we add to make it a perfect square

We take the coefficient of x

b

Divide by 2

b/2

Then square it

(b/2) ^2

In this case, we are adding 64

(b/2) ^2 = 64

Take the square root of each side

sqrt((b/2) ^2) = sqrt(64)

b/2 = ±8

Multiply each side by 2

b/2*2 =  ±8 *2

b = ±16
