Answer:
D. 6x-14
Step-by-step explanation:
So first we would do 3x^2+3x^2-5x^2
That would all cancel out so that would be 0.
Next we would do 3x-4x+7x, this would equal to 6x
Finally we would do -4-8-2, this would be equal to -14
Then the equation would be 6x-14
All you have to do is combine like terms.
Hope this helped!
Answer:
2. Alex sent the questionnaire only to those who live near her.
Step-by-step explanation:
Given scenario is :
Alex is conducting a survey for a car company. She decides to start by interviewing some people in her neighborhood.
She prepares a questionnaire and emails it to 50 neighbors who own cars. Of those neighbors, 24 respond.
We can see that Alex sent the questionnaire to only her neighbors or people who live near her, so this will be the reason the sample will be biased.
£1=100p
100-22=78p
He gets 78p
The area would be 50.27 inches
