Answer:
-63
Step-by-step explanation:
The opposite, or additive inverse of a number is found by changing the sign of the number. With the exception of zero, a number and its opposite (additive inverse) sum to zero.
If we call the number "x" then:
x*25%=21
x*25/100=21
x=21*4
x=84

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)
