What is the simpler form of (2k²− k+ 3) + (5k²+ 3k +7)?

Mathematics

Kryger [21]3 years ago

Answer: 7k^2+2k+10

Step-by-step explanation: To simplify this, you need to combine like terms, which are just the numbers that have the same variables and exponents. Combine 2k^2 and 5k^5 and it is 7k^2 (Just add the coefficient). Then do 3k -k, which is 2k. k just represents 1, so basically, 3-1. Finally, 7 + 3, which is 10. Then, combine the results to form an expression, which is 7k^2+2k+10.

We have A(1, 4)

reflected across the x-axis: (1, -4)

and then reflected across the y-axis: A'(-1, -4)

At the beginning of the day the stock market goes up 30 1/2 points. At the end of the day, the stock market goes down 100 3/4 po
Akimi4 [234]
Well, is namely their difference, so, let's first convert the mixed fractions to "improper", and subtract.

\bf \stackrel{mixed}{30\frac{1}{2}}\implies \cfrac{30\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{61}{2}}&#10;\\\\\\&#10;\stackrel{mixed}{100\frac{3}{4}}\implies \cfrac{100\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{403}{4}}\\\\&#10;-------------------------------\\\\&#10;\cfrac{61}{2}-\cfrac{403}{4}\impliedby \textit{so our \underline{LCD is 4}}\implies \cfrac{(2\cdot 61)~-~(1\cdot 403)}{4}&#10;\\\\\\&#10;\cfrac{122-403}{4}\implies \cfrac{-281}{4}\implies -70\frac{1}{4}

A circular garden has a diameter of 6 feet. Which of the following is closest to the area of the garden?
oksian1 [2.3K]
The answer to this problem is 'B'.

This is because to find the area of a circle your formula is
A = 3.14•r²
So your first step is

1. Find the radius by dividing the diameter (6) by 2
6/2 = 3 Radius= 3

Now that you have found the radius (3) plug the number in the formula
2. A = 3.14•3²
OR
A = 3.14•3•3

Finally, solve the last step - Find the area
3.14 • 3 • 3 = 28.26
A = 28.26
