Answer:
Step-by-step explanation:
The way you solve this equation is by substituting in the values we know:
3[(2x + 5) - (7x-1)]
Then you have to simplify:
3(-5x + 6)
And then you multiply:
-15 + 18
Answer:
Step-by-step explanation:
Compare the powers, p = 6
Answer:
Step-by-step explanation:
= x²(-3 +5) +y²(2 -3) +5xy -2y
= 2x² -y² +5xy -2y
a) there are 4 terms in the simplified expression
b) 2 terms have negative coefficients (-y² and -2y)
