Answer:
im pretty sure it is 2
Step-by-step explanation:
What is the algebraic expression?
28 degrees, 50 degrees, 60 degrees, 70 degrees
It would be 2/3 because u add the one yellow and three purple to make 4 (put that on the numerator) and the 6 would go on the denominator to make 4/6 then u divide each by two to reduce to get 2/3
You can remove the parentheses:-
= 7q^3r^2 + 5qr^2 + 23q + −5qr^2 − qr^2 − 11q − 4q^3r^2 ( because there is + outside)
Bring like terms together
= 7q^3r^2 − 4q^3r^2 + 5qr^2 − 5qr^2 − qr^2 + 23q − 11q
= 3q^3r^2 - qr^2 + 12q answer
