Answer:
B. 12x + 8
Step-by-step explanation:
2x + 5 + 4x - 1 + 2x + 5 + 4x - 1
<em>Combine like terms.</em>
6x + 5 - 1 + 2x + 5 + 4x + 1
8x + 5 - 1 + 5 + 4x - 1
12x + 5 - 1 + 5 - 1
12x + 10 - 1 - 1
12x + 10 - 2
<em>Subtract 2 from 10 to get 8.</em>
12x + 8
The perimeter of the rectangle is 12x + 8, which is B.
Answer:
6.76
Step-by-step explanation:
applying pythogorem theorem
a^2+b^2=c^2
5^2+b^2=13^2
25+b^2=169
b^2=169/25
b^2=6.76^2
b=6.76
Hi there! :)
<u><em>Answer:</em></u>
<u><em>=28b-57</em></u>
<u><em>*The answer must have a positive sign.*</em></u>
Step-by-step explanation:
<h2><u>Lesson: Distributive property</u></h2>
Distributive property: a(b+c)=ab+ac
First, you expand or multiply by the numbers from left to right.
It change positive to negative sign.
Finally, you add/subtract by the numbers from left to right.
It change positive to negative sign.
<em><u>Final answer is 28b-57</u></em>
I hope this helps you!
Have a nice day! :)

Part A) Divide 3 over 18.99 and we get 3/18.99 = 0.15798 approximately. So for this choice, we have roughly a 15.798% discount
Part B) The discount here is 10%. So far, discount A is better
Part C) The discount here is 15%. Discount A is also better because 15.798% is larger than 15%
Part D) Convert 1/4 to decimal form to get 0.25 and then move the decimal point 2 spots to the right to get 25%. So 1/4 = 25%. The discount here is 25%. This discount (of 25%) is much better than discount A.
Store 5 has the best discount since 25% is the largest among all the percentages.
Answer: Choice D)
