Answer:
4x⁴y
Step-by-step explanation:
Square the -x
2x·2xy·(-x)²= 2x·2xy·x²
Use the commutative property of multiplication to rearrange the order
2x·2xy·x² = 2·2·x·x·x²·y
Use the associative property of multiplication to combine like terms
2·2·x·x·x²·y = ( 2·2)·(x·x·x²)·y
Simplify
( 2·2)·(x·x·x²)·y = 4x⁴y
Union of two sets R and S is the set which contains all element, which are in either set R or S. The symbol for union is ∪, so t<span>he </span>union of two sets is written as R∪S.
<span>In our case, the sets are:
R = {10, 15, 20}
S = {20, 25}
The union for the sets R and S are:
</span><span>D. {10, 15, 20, 25}
Intersection on the other hand is the set that contains the elements that belong both in set R and set S. </span>
27% decrease. If you divide 1102 from 806 you get 0.731. When you multiply this by 100 to find the percent (73.1) and then subtract it from 100 (100-73)you get the percent decrease(27)
