Answer:
-3
Step-by-step explanation:
-12(x-12)=-9(1+7x)
-12x+144=-9-63x
-12x+63x=-9-144
51x=-153
x=-153/51=-3
25c - 5
Simplify all of the answer choices & see which one is correct.
a) 5(5c - 1)
25c - 5
A) IS CORRECT.
b) 5(20c + 1)
100c + 5
B IS INCORRECT.
c) 5(5c)
25c
C IS INCORRECT.
d) 5(c -1 )
5c - 5
D IS INCORRECT.
Therefore, the correct answer is a) 5(5c - 1)

6)
2(9+10) = 38
2(5+6) = 22
P = 38+22=60 in
14)
9 x 10 = 90
6 x 5 = 30
A = 90+50 = 140 in^2
