# 1.3x (2x - 5)2.(x + 2y)23. (x - 3)(x + 2)4.(3x + 2y) (x + 3y)5. (x - 4)(x + 4)​

1.3x (2x - 5)1.) -9. Not now yet:2 (x + 2y)23. (x - 3)(x + 2)4.(3x + 2y) (x + 3y)5. (x - 4)(x + 4)

Step-by-step explanation:

I hope it will help u...

Step-by-step explanation:

1.C

2.A

3.D

4.B

5.E

Solution-

1. 3x ( 2x - 5 )

= 6x² - 15x

C

2. (x + 2y ) ²

(x + 2y ) ( x + 2y )

= x² + 2xy + 2xy + 4y²

= x² + 4xy + 4y²

A

3. ( x - 3 ) ( x + 2 )

= x² + 2x - 3x - 6

= x² - x - 6

D

4. ( 3x + 2y ) ( x+ 3y )

= 3x² + 9xy + 2xy + 6y²

= 3x² + 11xy + 6y²

B

5. ( x - 4 ) ( x + 4 )

= x² + 4x - 4x - 16

= x² - 16

E

i don’t know what the answer is i wish i could help

Therefore, kathy is x + 16. (note that since lisa is 16 years younger than kathy, you must add 16 years to lisa to denote kathy's  age.) now, use the  problem  to set up an equation.
