Answer:42000
Step-by-step explanation:
There is no number higher than 5 after the thousands so you would keep it the same
Answer:
25%=7 75%=21 100%=28 125%= 35 150%=42
(8x^2-9y^2-4x)+(x^2-3y^2-7x)
First, get rid of the parentheses and combine like terms
(8x^2+x^2)(-9y^2-3y^2)(-4x-7x)
9x^2-12y^2-11x is your answer
