Answer:
Choice D
Step-by-step explanation:
After writing the data down seperate the values according to the x-axis on the graphs. You will find that 6 people chose between 0 to 3, 4 people chose between 4 to 7, 3 people chose between 8 to 11 and 2 people chose between 12 to 15.
Let the two integers be x and x+1
(x+1)^2-x^2=21
x^2+2x+1-x^2=21
2x+1=21
2x=20
x=10
then x=10, x+1
10+1=11
the two integers are 10, 11
Answer:
Saving (Start) = 1000

Answer:
Step-by-step explanation:
<u>Let's check his work by simplifying the given expression.</u>
- 2(x - 2) - 2(3)
- => 2x - 4 - 6
- => 2x - 10
When I compare Marty's result and this result, they are un-equal. Hence, Marty is incorrect.
<u>Marty's mistake</u>
- Marty must've got the problem wrong because of not understanding the distributive property.
- He probably forgot to multiply -2 by 2. Instead, he only subtracted 2 when he should've subtracted 4 from 2x.
