Answer:
x=15
y=18
Step-by-step explanation:
then x+y=33
and 2x+5y=120
then x=33–y
since 2x+5y=120
then 2(33–y)+5y=120
then 66–2y+5y=120
then 66+3y=120
then 3y=120–66
then 3y=54
then y=54/3
then y=18
then x=33–18=15
Answer:
<em>the answer is c</em>
( 2 x + 3 y ) ( 2 x − 3 y ) is the factored form of the expression
Step-by-step explanation:
- 4 x 2 − 9 y 2 can be also written as ( 2 x ) 2 − ( 3 y ) 2
- Now, as per identity: a 2 − b 2 = ( a + b ) ( a − b )
- So , in case of our expression a = 2 x , b = 3 y ( 2 x ) 2 − ( 3 y ) 2 = ( 2 x + 3 y ) ( 2 x − 3 y )
