Answer:
x = -4 ;
Step-by-step explanation:
6(x+3)=2(2x+5)
Distribution
6x+18 = 4x + 10
Subtract 4x on both sides
2x+18 = 10
Subtract 18 on both sides
2x = -8
Divided by 2
x = -4
Now if we have to substitute the value of X
6(-4+3)=2(-8+5)
Parenthesis first
6(-1) = 2(-3)
-6 = -6
23.78
CAH
x/25
cos18=x/25
25cos18=x
x=23.78
0
0 is the identity element under addition for the real numbers.
7x + 3(x-2) - 4x + 8
7x + 3x - 6 - 4x + 8
6x + 2
