2x^3−7x^2+16x−15

Step-by-step explanation:

(2x−3)(x^2−2x+5)

=(2x+−3)(x^2+−2x+5)

=(2x)(x^2)+(2x)(−2x)+(2x)(5)+(−3)(x^2)+(−3)(−2x)+(−3)(5)

=2x^3−4x^2+10x−3x^2+6x−15

Which key correctly represents the information below?

A) 11 | 2 = 12
B) 1 | 2 = 12
C) 11 | 2 = 112
D) 11 | 2 = 13

Answers

Answer:

The correct answer is C) 11 | 2 = 112

Step-by-step explanation:

That is because that is how these kinds of stem and leaf plots work. You add the number on the left to each individual number of the right. For example, the numbers in row 11 are actually:

112, 112, 115, 118.

The reason why we have stem plots is that it removes the need to write the 11 at the beginning of the number and lets you interpret and analyze the data more easily.

Stemplots are also pretty annoying and useless, and something you'll basically never use, so don't worry if they don't make much sense :)

C) 11 | 2= 112 the answer

Simplify: 18(5)

You can see the picture for the steps but I’m sure the answer is -72

Answer:

x = -72

Step-by-step explanation:

Using algebra:

⇒ [tex]-\frac{x}{8} -11 = 2[/tex]  (First add 11 to both sides of "=")

⇒ [tex]-\frac{x}{8} =9 (11 + -2)[/tex] (The multiply both sides by "8")

⇒ [tex]-x = 9*8[/tex] (Lastly the answer is 72 when x-value is negative, so when x-value will be positive the answer will be opposite of 72 which is -72)

⇒ [tex]x = -72[/tex]

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with similar chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks associated with the filling of different atomic orbitals. #2-118

Walden gives the pizza delivery person an $8.00 tip, which was 12% of the cost of his pizzas. How much was the total amount that Walden spent? Round your answer to the nearest cent.

ANSWERS WITH WEIRD FILE THINGYS WILL BE REPORTED IMMEDIATLY

Answers

Answer:

$17

Step-by-step explanation:

Tip = $8.00

Pizzas cost:

First you have to do 12% of $8.00 which = $0.96

Then you have to add the $0.96 to the $8.00 which = $8.96

Total = $8.00 + $8.96

         = $16.96

then round it to nearest cent which is $17

Answer:

$74.67

Step-by-step explanation:

$8 was 12% of the cost of the pizzas, so we have to add that to the initial cost. The initial cost can be found by (8*100)/12, which would be $66.67. Since we need to find the total amount of money spent, we have to add the initial cost of pizzas and the $8 tip, which is 12% of that. Final answer is $74.67

Find the value of x and find whether the angles or supplementary or complementary.

Answers

Answer:

1) x = 31

2) Both angles add up to be a supplementary angle (an angle who's sum is 180° altogether).

Step-by-step explanation:

1) Since both angles add up to be a supplementary,

→ equation 1 + equation 2 = 180

→ (3x + 25) + (2x) = 180

Solving by applying algebra will give the answer "x = 31".

Likewise, his wife, Martha Washington, could also be considered the "Mother of America," as demonstrated by her roles as the general's wife and the first lady. During the American Revolution, Martha Washington earned the title of "Mother of America" for her caring nature as the general's wife. She was also very brave. Despite the danger of kidnapping, Martha refused to abandon her home, Mount Vernon, in Virginia. When Martha did leave the plantation for periods of time, she traveled to the military camps where Washington was staying. First, Martha had to be vaccinated so that she would not suffer from smallpox. Once she was inoculated, Martha made the risky trip to camp. British and American soldiers roamed the countryside, and capture was a real possibility. Nevertheless, Martha arrived at each winter camp. She acted as confidant and secretary to George Washington, who believed that her presence was crucial. She encouraged the soldiers, helped their wives, and comforted those who were wounded. One of her key roles was also to entertain important visitors to the camp. Occasionally, Martha Washington even represented George at events he could not attend. Martha used her position to contribute to fundraising efforts for military supplies in 1780 and knit socks for the soldiers herself. Overall, her care and attention to others' needs made her the "Mother of America" during the American Revolution. What reason does the author provide to support the point that Martha Washington should be considered the "Mother of America"? a Her bravery when being inoculated from smallpox b Her care and attention to others' needs as the General's wife c Her fear of being kidnapped by British soldiers d Her willingness to knit socks for soldiers at the military camp what is the formula of general fertility rare How many mL of 0.715 M HCl is required to neutralize 1.25 grams of sodium carbonate?
