Help would be nice! Thanks

Number one is 4p+8-9. 8-9= -1 So, 4p-1. Divide both by 4. p=.25

1a. 4(p+4)-9 = (4p+16)-(9) = 4p+7

2a. 10a+5-7a = (10a-7a)+(5) = 3a+5

3a. 10+9v-10-6v = (10-10)+(9v-6v) = 0+3v = 3v

4a. (t+2)-6 = t+2-6 = t-4

5a. 10-3x+7x+5+9x = (10+5)+(-3x+7x+9x) = 15+13x

6a. 5b-3b = 2b

7a. 7s-4+5-7s = (7s-7s)+(-4+5) = 0+1 = 1

1b. 3+(8b+5) = 3+8b+5 = (3+5)+8b = 8+8b = 1+b

2b. 2-3p+7p+10+p = (2+10)+(-3p+7p+p) = 12+5p

3b. 10+2(t+6) = 10+2t+12 = 22+2t = 11+t

4b. 7-8p+5p+10+6p = (7+10)+(-8p+5p+6p) = 17+3p

5b. 10+7(6y+5) = 10+42y+35 = (10+35)+42y = 45+42y

6b. w^4*w^2 = w^6

7b. 6p+5p = 11p

i dont know
