What is the correct answer?
Svetlanka [38]

Answer:

Terms must have the same variable (letter) and the same exponent (little number)

(7x² +3y+ 5) +(9x²+11y- 2)

Opening bracket

7x²+3y+5+9x²+11y-2

keeping like terms together

7x²+9x²+3y+11y+5-2

Since terms having same variable and exponent can be subtracted, added,divided and multiplied

So

Solving like terms we get

<u>16x²+14y+3</u> which is a correct answer.

2*8*5=2*5*8 identify the property that is shown
ira [324]
The property shown is commutative multiplication.  This property says that the product of two factors is not affected by the order in which they're multiplied.  In this case, the product remains the same i.e.,  2*8*5 = 80 while 2*5*8 <em>also </em>equals 80.
