Can someone help me in this? a^2-ab-b-1

Answer:

(a + 1) (a − b − 1)

Step-by-step explanation:

I assume you're trying to factor the expression?  If so, use quadratic formula to find the roots.

a = [ -(-b) ± √((-b)² − 4(1)(-b−1)) ] / 2(1)

a = [ b ± √(b² + 4b + 4) ] / 2

a = [ b ± (b + 2) ] / 2

a = -1 or b + 1

(a − (-1)) (a − (b + 1))

(a + 1) (a − b − 1)

Una librería consta de 5400 libros repartidos en 3 estanterías
pishuonlain [190]

Answer:

B = 900 Libros

A = 2700 Libros

C = 1800 Libros

Step-by-step explanation:

A = 3B

2B = C

A + B + C = 5400

3B + B + 2B = 5400

6B = 5400

B = 5400 / 6

B = 900 Libros

A = 3B

A = 3(900)

A = 2700 Libros

C = 2B

C = 2(900)

C = 1800 Libros

It will take one person for the venues to equal the same amount. This is simply done by multiplying 1 x the per person amount then adding it to the reservation cost.

An equilateral triangles has 3 equal sides and 3 equal angles.
All the angles of an equilateral triangle have a measure of 60 degrees.

Using the Pythagorean theorem, the length of the hypotenuse squared is the length of one leg squared plus the length of another leg squared.

Here's the equation for the Pythagorean theorem.
Let c be the length of the hypotenuse.
Let a and b be the length of the two legs.
a^2 + b^2 = c^2 

Have an awesome day! :)
