Question 1-

Three friends, Martin, Tyreese, and Braydon, are collecting donations to help in their community's clean-up initiative. Their total contribution goal is represented by the expression 7x^2 − 4xy + 8. The friends have already collected the following amounts:


Martin: 5xy + 16


Tyreese: x^2


Braydon: 4x^2 − 7


Which expression represents the amount of money the friends still need to collect to meet their goal?


A- 2x^2 − 9xy − 1

B- 2x^2 + xy + 17

C- 5x^2 + 5xy + 9

D- 12x^2 + xy + 17


Question 2-


The three sides of a triangular fence have lengths 2x + 3, y − 6, and 4x − 3. What is the total perimeter?


A- 2x + y − 6 feet

B- 6x + y feet

C- 6x + y + 6 feet

D- 6x + y − 6 feet


you can answer it by putting question 1- *answer* question 2- *answer* or somthing like that thank you

Answer 1

Question 1- A- 2x^2 − 9xy − 1

Question 2- D- 6x + y − 6 feet

Explanation:

I took the test and got it right.

for question one- add Martin, Tyreese, and Braydon together then subtract that from their goal which was 7x^2 − 4xy + 8 and you'll get A- 2x^2 − 9xy − 1

for question two- just add 2x+3, y-6, and 4x-3 together and you'll get D- 6x+y-6 because to find the perimeter you just add all the sides together so

so therefore question 1 is A- 2x^2 − 9xy − 1 and question 2 is D- 6x + y − 6 feet
