Combining the like terms, the simplified polynomials are given as follows:

a) 4x² - 14x + 17

b) -5x² - 20x + 8

<h3>How are polynomials simplified?</h3>

Polynomials are simplified combining the like terms, that is, adding these numbers with the same variable.

Item a:

4(x - 2)(x + 1) - 5(2x - 5)

Applying the distributive property:

4(x² - x - 2) - 10x + 25

4x² - 4x - 8 - 10x + 25

Combining the like terms:

4x² - 4x - 10x - 8 + 25

4x² - 14x + 17

Item b:

-5(x + 2)² + 28

-5(x² + 4x + 4) + 28

-5x² - 20x - 20 + 28

-5x² - 20x + 8

Arlecino [84]

Answer:

the probability that the ext order will be shrimp = 27.78%

Step-by-step explanation:

Vegetable 333

Chicken 666

Pork 222

Beef 222

Shrimp 555

total = 1,998

P (shrimp) = 555 / 1,998 =  0.2777 or 27.78%

in case the numbers in the orders were:

Vegetable 3

Chicken 6

Pork 2

Beef 2

Shrimp 5

total = 18

P (shrimp) = 5 / 18 =  0.2777 or 27.78%

The probability of an event happening is just the number of times that event occurred divided by the total number of events that took place.

Patrick pizza parlor is famous for its giant circular pizza, which has an area of 1519.76 square inches. Approximately what is t
Misha Larkins [42]

Answer:

Step-by-step explanation:

Patrick pizza parlor is famous for its giant circular pizza, which has an area of 1519.76 square inches. The pizza is circular in shape. The formula for determining the area of a circle is expressed as

Area = πr^2

π is given as 3.14

Therefore,

1519.76 = 3.14 × r^2

r^2 = 1519.76/3.14 = 484

Taking square root of both sides of the equation, it becomes

r = √484 = 22 inches

Diameter = 2 × radius.

Therefore, the diameter of the giant pizza is 2 × 22 = 44 inches

Alternate interior angles are equal.
2x - 10 = 65 - x
2x + x = 65 + 10
3x = 75
x = 75/3 = 25
x = 25.
