Answer:

A. x^3 − 9x^2 + 14^x + 24

Step-by-step explanation:

(x − 4)(x^2 − 5x − 6) = x(x^2 − 5x − 6) -4(x^2 − 5x − 6)

= x^3 -5x^2 -6x -4x^2 +20x +24

= x^3 +x^2(-5-4) +x(-6+20) +24

= x^3 − 9x^2 + 14x + 24 . . . . matches the first choice

x2-16= -2x - 1

Please help

Answers

Answer:

The solutions are -5 and 3.

Step-by-step explanation:

[tex]x^2 - 16 = -2x-1[/tex]

[tex]x^2 - 16 +2x+1=0[/tex]

[tex]x^2 +2x-15=0[/tex]

Factoring the quadratic expression:

[tex](x+5)(x-3)= x^2 +2x-15=0[/tex]

So,

[tex]x+5 = 0 \implies x =-5[/tex]

[tex]x-3 = 0 \implies x =3[/tex]

Which expression is equivalent to 8c + 6 - 3c - 2 ?

A)5c + 4

B)5c + 8

C)11c + 4

D)11c + 8

Answers

Answer:

I believe the answer is 5c + 4.

Step-by-step explanation:

The first step in simplifying expressions like this is to combine the values with the same coefficient and rearrange them so that they are next to each other in the expression. When you do this, you also have to keep the operation that comes before it if possible. 8c + 6 -3c - 2 will be turned into 8c - 3c + 6 - 2. Now you can simplify the expression in different parts. 8c - 3c = 5c, and 6 - 2 = 4. Keep the addition operation in the middle and combine the numbers:

5c + 4.

The second option, 2 is a prime number, but not odd

Step-by-step explanation:

A prime number is a result of two other whole numbers multiplied by themselves. There is no whole number that you can multipy by itself to get 2 because 1 × 1 = 1 and 2 × 2 = 4. Therefore, it is a prime number. But, that does not mean it is an odd number because odd numbers are 1, 3, 5, 7, etc. and even numbers are 2, 4, 6, 8, etc.

Sir Roger Bannister, the first man to break the four-minute-mile record, knew what it was like to break barriers.Learning a Passion Roger Bannister was born in Harrow, England, in 1929. Since his parents couldn't afford to send him to college, he worked to win scholarships to study medicine at Oxford. Bannister had two loves: studying medicine and running track. He worked hard to do well at both. Because of his studies, Bannister had less time for track practice than other athletes. Most athletes trained at least six days a week. Bannister trained only two to three times a week. In the 1952 Olympic Games, Bannister ran the 1500m race but finished fourth. Many said this was due to his lack of training. Bannister decided it was time to get serious. He focused on doing what everyone in the world thought was impossible. He wanted to break the four-minute-mile barrier.Setting a Goal No one in history had ever run a mile in less than four minutes, although several had tried. For decades, physicians believed that running a mile too fast would cause heart failure. Bannister knew he could set a new world record by working hard. Bannister believed that pushing himself beyond the pain would make him a winner. That is just what Bannister did on May 6, 1954, at Iffley Road Track in Oxford. On a cold, wet track, Roger Bannister broke the four-minute-mile barrier with a time of 3:59.4. Two other runners helped him set a fast pace. Then Bannister relied on his training to run the first three laps of the track in 3:01. During the final lap of the race against the clock, Bannister knew he could finish the race in less than 59 seconds. He broke away from the other runners and flew down the last two curves of the track at record speed. As he crossed the finish line, he collapsed into the arms of his friend Reverend Nicholas Stacey. Bannister was out of breath and out of energy, but he knew he had broken the world record. Bannister accomplished a great moment in history that day. After breaking the four-minute-mile barrier, Bannister competed in a few more races. He ran his personal record of 3:43.8 in the 1500m in the European Championship. That was Bannister's last race. In August of 1954, he retired at the age of 25 to focus on what he considered his true contribution to societyhis research in the field of neurology, the study of the nerves and the nervous system.Making a Difference In 1975, two decades after his feat, Roger Bannister was knighted by the Sports Council of England. He had done what no man thought was possible. However, Bannister knew his athletic glory was fleeting. He felt that his work as a neurologist was the real accomplishment of his life. For over 40 years, he worked in neurology, helping patients who suffered serious neurological disorders. To honor his work and dedication as a neurologist, St. Mary's Hospital in London named a lecture hall after Dr. Bannister. In the lecture hall, the famous stopwatch used to time Bannister's mile is on display. In July of 2012, Bannister was honored to be elected as one of the Olympic torchbearers. He carried the flame into the Oxford track stadium that was named for him. Of his neurology career and his track achievements, as the greatest runner ever, Bannister claims that working hard is the secret to his success.10What can be inferred by referring to the timeline? A. Bannister was more well known as a neurologist than as a track and field star. B. Bannister did not value his time as a runner and never participated in sports again. C. Despite retiring from track and field at a young age, Bannister was still involved with sports throughout his life. D. After retiring from track and field at a young age, Bannister continued to run. How do you tell someone you don't agree with them? A.J'ai raison B. Je suis d'accord C. J'ai tort D.Je ne pas d'accord. A patio 44, feet wide is being constructed next to a house.
