Ok look person that keeps answering Im sorry hut I gues u can tell why Im literally fai-ling math, question is: add the polynomial expressions using the horizontal format

Answer:

p(- 1) = 2 and p(1) = 2

Step-by-step explanation:

Substitute x = - 1 and x = 1 into p(x), that is

p(- 1) = (- 1)² + 1 = 1 + 1 = 2

p(1) = 1² + 1 = 1 + 1 = 2

Answer:

16

Step-by-step explanation:

Here we will show you how to calculate 6 divided by 3/8. We will give you the answer in fraction form and in decimal form.

Here is 6 divided by 3/8 displayed mathematically in colors:

6

 ÷    

3

8

The numbers in 6 divided by 3/8 are labeled below:

6 = whole number

3 = numerator

8 = denominator

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

6 x 8

3

 =    

48

3

Thus, the answer to 6 divided by 3/8 in fraction form is:

48

3

To make the answer to 6 divided by 3/8 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

48 / 3 = 16

The answer is rounded to the nearest two decimal points if necessary.

48/3 can be simplified to 16/1.

16/1 is an improper fraction and should be written as 16.

Answer:

? = 64°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

The third angle in the triangle on the right is

third = 180° - (84 + 36)° = 180° - 120° = 60°

Thus the third angle in the triangle on the left is

third = 90° - 60° = 30° , then

? = 180° - (86 + 30)° = 180° - 116° = 64°

Step-by-step explanation:

Answer:

Let’s assume a,b,x real. Then all we require of y is y2 is real, so y

can be real or purely imaginary, but not an arbitrary complex number.

The hard question in these is always, do we need ±

? Here the answer is yes. It’s basically asking is there one solution or two, and in this problem we have two.

Solve for y

Step-by-step explanation:

Conversion a mixed number 3 3/

4

to a improper fraction: 3 3/4 = 3 3/

4

= 3 · 4 + 3/

4

= 12 + 3/

4

= 15/

4

To find new numerator:

a) Multiply the whole number 3 by the denominator 4. Whole number 3 equally 3 * 4/

4

= 12/

4

b) Add the answer from previous step 12 to the numerator 3. New numerator is 12 + 3 = 15

c) Write a previous answer (new numerator 15) over the denominator 4.

Three and three quarters is fifteen quarters

Conversion a mixed number 2 2/

5

to a improper fraction: 2 2/5 = 2 2/

5

= 2 · 5 + 2/

5

= 10 + 2/

5

= 12/

5

To find new numerator:

a) Multiply the whole number 2 by the denominator 5. Whole number 2 equally 2 * 5/

5

= 10/

5

b) Add the answer from previous step 10 to the numerator 2. New numerator is 10 + 2 = 12

c) Write a previous answer (new numerator 12) over the denominator 5.

Two and two fifths is twelve fifths

Multiple: 15/

4

* 12/

5

= 15 · 12/

4 · 5

= 180/

20

= 9 · 20/

1 · 20

= 9

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(180, 20) = 20. In the next intermediate step , cancel by a common factor of 20 gives 9/

1

.

In words - fifteen quarters multiplied by twelve fifths = nine.

Answer:

−6x−19y−56

Step-by-step explanation:

−8(2x)+5(2x−12)+−2(5y−2)+(−3)(3y)

Multiply −8 and 2 to get −16. Multiply −3 and 3 to get −9.

−16x+5(2x−12)−2(5y−2)−9y

Use the distributive property to multiply 5 by 2x−12.

−16x+10x−60−2(5y−2)−9y

Combine −16x and 10x to get −6x.

−6x−60−2(5y−2)−9y

Use the distributive property to multiply −2 by 5y−2.

−6x−60−10y+4−9y

Add −60 and 4 to get −56.

−6x−56−10y−9y

Combine −10y and −9y to get −19y.

−6x−56−19y

Answer:

$25.50

Step-by-step explanation:

35 - 9.5 = x

25.5 = x

Answer:

Step-by-step explanation:

Let p=pop corn and x=tickets.

Because they have $9.50 on popcorn you should subtract 9.50 from 35. This gives you $25.50 dollars.

Because you know that they used the rest of the money to but tickets, they spent $25.50 on tickets

Therefore the equation should be 35-9.50=x or x=35-9.50
