Question

I need help on this plss

Answer 1

B.) 3x+2

Explanation:

2(7x+10)+2y=20x+24

14x+20+(6x+4)=20x+24 because there are two sides where you have to

20x+14 multiply the height and width by two o account for

both the actual number before multiplied was 3x+2

x= 1 /3 y+ −2/ 3

x=3y+2

Answer 2

(20x+24)-2(7x+10)

(20x+24)-(14x+20)

6x+4 but thats for 2 sides so 3x+2

B

Check:

x=3

3*3+2=11*2=22

7*3+10=31*2=62

62+22=84

20*3+24=84
