4 - 2(x + 3) = 5
4 - 2x - 6 = 5
-2x - 2 = 5
-2x = 5 + 2
-2x = 7
x = -7/2 or = -3 1/2

Investigate the link between Pascal's triangle and 2 and its powers
lina2011 [118]

Answer:

Outside of probability, Pascal's Triangle is also used for: Algebra, where coefficient of polynomials can be used to find the numbers in Pascal's triangle.  Pascal's Triangle is an arithmetical triangle you can use for some neat things in mathematics.

The entries in Pascal's triangle are actually the number of combinations of N take n where N is the row number starting with N = 0 for the top row and n is the nth number in the row counting from left to right where the n = 0 number is the first number.

The mathematical formula for the number of combinations without repetition is N!/(n!(N-n)!).

Step-by-step explanation:

To construct Pascal's triangle, start with a 1. Then, in the next row, write a 1 and 1. It's good to have spacing between the numbers. In the third row, we have 1 and 1 on the outside slopes. The 2 comes from adding the two numbers above and adjacent. Thus, we are adding the number on the left, 1, with the number on the right, 1, to get 1 + 1 = 2.

In the next row, the 3 comes from adding the 1 and the 2. This particular Pascal's triangle stopped at 1 5 10 10 5 1, but we could have continued indefinitely.

Lily's basketball team won 4/5 of their games. Lily scored points 2/3 of the games her team won. In waht fraction of her team's winning games did Lily score points?

Answer: =D.\frac{5}{6}

Solution:

\frac{ 2  }{ 3  }   \div   \frac{ 4  }{ 5  }  =

\frac{2}{3}\times \left(\frac{5}{4}\right)

\frac{2\times 5}{3\times 4}

\frac{10}{12}

=\frac{5}{6}

I reduced the fraction \frac{10}{12} into the Lowest terms by doing extracting and cancelling out the 2

=\frac{5}{6}

So the answer is letter D.\frac{5}{6}

Week 12<br> Please answer with clear instructions so that i can apply this to other questions
OLEGan [10]

Answer:

94.2m^2

Step-by-step explanation:

The formula for SA of a cone is...

\pi (r)(h)+\pi (r)^2

Fill in what you have

\pi (3)(7)+\pi (3)^2

Pi is 3.14 for our purposes

\pi (3)(7)+\pi (3)^2\\3.14(3)(7)+3.14(3)^2

Then solve

21(3.14)+9(3.14)\\\\94.2m^2
