Answer:

[tex]x^{3} -x^{2} -5x-3[/tex]

Step-by-step explanation:

you use distributive property for this, or you can do the box method

distributive:

[tex]x(x^{2} +2x+1)-3(x^{2} +2x+1)[/tex] (you multiply the second equation by x-3)

then distribute, or multiply everything

[tex]x^{3} +2x^{2} +x-3x^{2} -6x-3[/tex]

then collect like terms

[tex]x^{3} -x^{2} -5x-3[/tex]

Actually Welcome to the Concept of the Angle sum property of a triangle :

here, addition of all angles of triangles should be 180° , and hence,

6x = 120°

===> x = 20°

hence, option B.) is correct.

B.) (x+5) °+(3x) °+(2x+55) °=180° ; x=20°

Answer:

x=-7

Step-by-step explanation:

Answer:

x=11

Step-by-step explanation:

5+3x-37=6x+23-8x

add like terms

-32+3x=-2x+23

add 2x to both sides

-32+3x+2x=23

add 32 to both sides

3x+2x=23+32

add like terms

5x=55

divide by 5 on both sides

x=11

Answer:

Tallest = Morgan

Shortest = Suzanna

Step-by-step explanation:

Assuming Latisha = 1

0.8 is less than 1, meaning it's 80% the height of Latisha, so this means Suzanna is shorter than Latisha.

1.09 is more than 1, Morgan is taller than Latisha.

Morgan is tallest and Suzanna is shortest, Latisha in the middle.

Answer:

.4321

Step-by-step explanation:

move the decimal to the left four times

We want to write four thousand three hundred twenty-one ten thousandths as a decimal​.

The number is:

4321.010

To do it, we need to understand what each place value represents, where the place values are the place of each digit in reference to the decimal point.

And for the right we have:

Of course, it continues in both ways, but this is enough to write our number.

We have:

"four thousand..."

Then the fourth digit at the left is a 4.

"... three hundred..."

The third digit is a 3.

"...twenty-one..."

The second digit is a 2, and the first is a 1.

For the right side, we do not have tenths, so the first digit at the right is a zero.

And "...ten thousandths"

We have a "10" in the second and third digits at the right of the decimal point.

Then our number is:

4321.010

Step-by-step explanation:

4k + 5 + 6k + 10 = 115  {Exterior angle property}

4k + 6k + 5 +10 = 115

         10k + 15 = 115

               10k = 115 - 15

               10k = 100

Answer:

There are three more square chocolates left

Step-by-step explanation:

We know that Irena breaks off 2 complete strips and eats 12 meaning each strip had 6 squares. Jack breaks off 9. So if we add all the squares into rows of 6, we get four strips of chocolate from the beginning. Since Jack and Irena obtained 21 chocolate squares altogether, we have 3 chocolate squares that are remaining. I hope this helps ;)

The number of Squares of chocolate left in the bar is; 15 squares

A square has 4 equal sides and since one row contains 6 squares because irena ate 2 complete rows that had 12 squares.

It means that each of the vertical height must also contain 6 squares as well.

Now, two rows are gone and so we now have 4 rows with vertical height of 4 squares. That is 24 squares left.

Now, Jack ate 9 squares and so;

Amount of squares left = 25 - 9 = 15

Answer:

[tex]b = 19[/tex]

Step-by-step explanation:

1) Add 7 to both sides.

[tex]b = 12 + 7[/tex]

2) Simplify 12 + 7 to 19.

[tex]b = 19[/tex]

Therefor the answer is, b = 19.

Answer:

Sample Response

Step-by-step explanation:

Use the inverse operation to isolate the variable. Undo the subtraction of 7 by adding 7 to each side of the equation. – 7 + 7 = 0, and 12 + 7 is 19. The solution is b = 19. Check the solution by substituting 19 for b in the original equation, and then simplify. 19 – 7 is 12 and 12 = 12 is a true statement, so 19 is the solution.
