Answer:
-3(-3x + 4) = 9x - 12
Step-by-step explanation:
-3( Ax + 4) = 9x - 12
-3Ax -12 = 9x - 12
Equating coefficients of x terms on both sides :
-3A = 9
A = -3
Therefore, -3(-3x + 4) = 9x - 12
3x+12=39
Minors 12 on both side
3x=27
Divide 3 on both side
X=9
Step-by-step explanation:
-16 + 3n = - 8 - 5n
Bringing like terms on one side
3n + 5n = - 8 + 16
8n = 8
n = 8/8
N = 1
Answer:
yes
Step-by-step explanation:
if it is a terminating decimal(a decimal that ends) it will be rational
C, a²+b²=c²
