Barnes and Noble is having a sale on books. Each book is $5.34. Alex bought 5 books. How much did he spend?
Answer:
The answer is 5.34 times 5, which is $27.70
how many time can 22 go into 30
Answer:
1 time
Step-by-step explanation:
This is the answer because:
1) 22 x 1 = 22
2) If we do 22 x 2, the number will become larger than 30
3) Therefore, 22 can only go one time into 30 because 30/22 = 1 R8

(m²+mn+n²)(m²-mn+n²)
Answer:
[tex]m^{4\\}[/tex]+[tex]m^{2}[/tex][tex]n^{2}[/tex]+[tex]n^{4}[/tex]
Step-by-step explanation:
If you're distributing each value, I would recommend you to use the lattice method so that you can work on it faster. Make sure to add the exponents instead of multiplying to have an accurate answer. Once your done then cross out the ones that would subtract to 0 which would leave you with [tex]m^{4\\}[/tex]+[tex]m^{2}[/tex][tex]n^{2}[/tex]+[tex]n^{4}[/tex] as your final answer if you did it properly.

Solve -2(x-5) + 3x = 2(x+3) + 17 *
Answer:
x=-13
Step-by-step explanation:
Hope this helped :)
Answer:
x = -13
Step-by-step explanation:
-2x + 10 + 3x = 2x + 6 + 17
x + 10 = 2x + 6 + 17
x + 10 = 2x + 23
10 = 2x + 23 - x
10 = x + 23
10 - 23 = x
-13 = x
x = -13
