Answer:

q = 1; r = 2; s = 3; t = 4; x = 5; y = 6

7. 2(x+4) + 10 = 2(5+4)+10 = 2*9+10=18+10=28

8. 3(4x) + 4 = 3(4*5)+4 =3(20)+4 = 60+4 = 64

9. 10(xy) = 10(5*6) = 10(30) = 300

10. 2(x + y) = 2(5+6) = 2(11) = 22

11. 3(rs) + 4(x) = 3(2*3)+4(5) = 3(6)+20=18+20=38

12. 2(q) + 2(x + t) = 2(1)+2(5+4) = 2+2(9) = 2+18=20

13. 6(3t + 4s) = 6(3*4 + 4*3)=6(12+12) = 6*24 = 144

14. 10(10x) + 10y = 10(10*5)+10*6 = 10(50)+60=560

15. x(xy) = 5(5*6)=5*30=150

16. r(s)(t) =2*3*4=6*4=24

17. (r)(s)(t)(x)(y) =2*3*4*5*6=24*30=720

18. 6(2x + 3Y) =6(2*5+3*6)=6(10+18)=6(28)=168

Answer:

7. 2(5 +4)+10

= 2(9) +10

= 18+10

= 28 answer

8. 3(4x) + 4

= 3(4x5)+4

=3(20)+4

=60+4

=64

9. 10(xy)

=10(5x6)

=10(30)

=300

10. 2(x + y)

=2(5+6)

=2(9)

=18

11. 3(rs) + 4(x)

=3(2x3)+4(5)

=3(6)+20

=18+20

=38

12. 2(q) + 2(x + t) =

=2(1)+2(5+4)

=2+2(9)

=2+18

=20

13. 6(3t + 4s)

=6(3x4+4x3)

=6(12+12)

=6(24)

=144

14. 10(10x) + 10y

=10(10x5)+10x6

=10(50)+60

=500+60

=560

15. x(xy)

=5(5x6)

=5(30)

=150

16. r(s)(t)

=2(3)x(4)

=6x(4)

=24

17. (r)(s)(t)(x)(y)

=(2)x(3)x(4)x(5)x)6)

=6x20x(6)

=120x6

=720

18. 6(2x + 3Y)

=6(2x5+3x6)

=6(10+18)

=6(28)

=168
