Answer:
4x^2+3x+y^2+30y+8
Step-by-step explanation:
given expression:
x^3+x(4x - x^2) + 3y^2 +12 - 4x^0 +2y(15 - y) + 3x
expand the terms we get:
x^3 + 4x^2 - x^3 + 3y^2 + 12 - 4 +30y - 2y^2 + 3x
bring all like terms together we get:
x^3 - x^3 + 4x^2 +3x + 3y^2 -2y^2 + 30y + 8
= 4x^2 + 3x + y^2 +30y + 8
Answer:
b.7a.10
Step-by-step explanation:
871,000 is the answer. It would've said the nearest ten thousand but you need to find the nearest "thousand". Try to be careful for these questions. They can be tricky.
