Answer:
1) 14 2) 6 3) 53 4)-2
Step-by-step explanation:
1) 15 - n/7 = 13
7*15 - 7*n/7 = 7*13
105 - n = 91
-n = 91 - 105
-n = -14
n = 14
2) 44 = - 4 + 8p
-8p = - 4 - 44
-8p = -48
-p = - 48/8
-p = 6
3) 21 - h= -32
-h = -32 -21
-h = -53
h = 53
4) -19 = 11b + 3
-11b = 19 + 3
-11b = 22
-b = 22/11
-b = 2
b = -2

Answer:
D is the correct answer
Step-by-step explanation:
Fifth row of Pascal pyramid is 1 , 5, 10, 10, 5 , 1
The expansion should always have n + 1 number of terms
Where n is the power
2a.) 8.8 x 4 = 35.2g
2b.) 35.2 x 30 = 1056g or 1.056kg
A) 2(1+2c)
2+4c = 2+4c
B) 6(14r-2t)
= 84r-12t
