Answer:

She will need 22 feet of ribbon

Step-by-step explanation:

The length of the border of ribbon is equal to the perimeter of the rectangular picnic blanket

The formula of the perimeter of a rectangle is P = 2(l + w), where l is its length and w is its width

∵ The long side of the blanket is 7 feet

∴ l = 7

∵ The short side of it is 4 feet

∴ w = 4

Use the formula of the perimeter above to find the perimeter of the blanket

∵ P = 2(l + w)

∴ P = 2(7 + 4)

- Add the numbers in the bracket

∴ P = 2(11)

∴ P = 22 feet

∵ The length of the border of ribbon is equal to the perimeter

    of the blanket

∴ The length of the ribbon is 22 feet

∴ She will need 22 feet of ribbon

Answer:

Step-by-step explanation:

The total number of outcomes the two fair number cubes are thrown is 36. This can be seen by counting the outcomes shown on the table.

a) for a sum of 4, there are only 3 possible outcomes. They are 3,2 2,2 and 1,3

Therefore, the probability of getting a sum of 4 will be

3/36 = 1/12

b) for a sum of 5, there are only 4 possible outcomes. They are 4,1 3,2 2,3 and 1,4

Therefore, the probability of getting a sum of 4 will be

4/36 = 1/9

c)for a sum of 6, there are only 5 possible outcomes. They are 5,1 4,2 3,3 2,4 and 1,5

Therefore, the probability of getting a sum of 6 will be

5/36 = 5/36

The probability that the sum of the results of the throw is 4,5 or 6 would be

1/12 + 1/9 + 5/36 = (3 + 4 + 5)/36 = 12/36 = 1/3

-7x - 2y = 19<br> 4x + y = -12<br> Solve the system
nalin [4]

-7x - 2y = 19

4x + y = -12

Set y equal to each other (opposite signs are fine and you could also set x equal instead of y)

-7x - 2y = 19

8x + 2y = -76

Add equations together

x = -52

Plug x value into an equation

4(-52) + y = -12

Solve for y

-208 + y = -12

y = 196

Hope this helps! ;)

Write the answer in standard form.
viktelen [127]

Answer and step-by-step explanation:

We learn that (a+b)^3 = a^3 + 3a^2b + 3ab^2 + b^3

So in this case, it would be:

= x^3 + (3*x^2*2) + (3*x*2^2) + 2^3

= x^3 + 6x^2 + 3x * 4 + 8

= x^3 + 6x^2 + 12x + 8

This is the standard form of the equation

Hope it help you :3
