1 answer:
inysia [295]3 years ago

Answer:

Step-by-step explanation:

Take the area of the yard and subtract from it the area of the pool.  In quadratic form, the area of the pool is

2x^2-x-28

Subtracting the area of the pool from the area of the yard:

3x^2-14x-5-(2x^2-x-28)

Since the negative in front of the parenthesis will change the signs inside:

3x^2-14x-5-2x^2+x+28

Combine like terms to get the area left after the pool goes in:

x^2-13x+23

Three orders are placed at a pizza shop. two small pizzas, a liter of soda, and a salad cost $14; one small pizza, a liter of so
mojhsa [17]
To determine the cost of each item, we need to set up equations. From the problem statement, we have three unknowns so we need three equations. We set up equations as follows:

let x cost of small pizzas
     y cost of soda
     z cost of salad
 
two small pizzas, a liter of soda, and a salad cost $14
2x + y + z = 14

one small pizza, a liter of soda, and three salads cost $15

x + y + 3z = 15

three small pizzas, a liter of soda, and two salads cost $22
3x + y + 2z = 22

Solving for x, y and z, we will have:

x = $ 5
y = $ 1
z = $ 3

For what value of x is the rational expression below undefined x-4/3x2-75
abruzzese [7]

The given expression is undefined when x = 5 OR x = -5

<h3>Undefined expression </h3>

From the question, we are to determine the value of x for which the given expression is undefined

The given expression is

x-4/3x²-75

An expression is undefined when the denominator equals zero

Thus, the expression is undefined when

3x² - 75 = 0

Now, we will determine the values of x in the equation above

3x² - 75 = 0

3x²  = 75

x² = 75/3

x² = 25

x = ±√25

x = ±5

Hence, the given expression is undefined when x = 5 OR x = -5
