Answer:
27
Step-by-step explanation:
3*3*3=27. 3*3=9 9*3=27
Step 1: Simplify both sides of the equation.
3(x−3)+5=3x+1+4
(3)(x)+(3)(−3)+5=3x+1+4(Distribute)
3x+−9+5=3x+1+4
(3x)+(−9+5)=(3x)+(1+4)(Combine Like Terms)
3x+−4=3x+5
3x−4=3x+5
Step 2: Subtract 3x from both sides.
3x−4−3x=3x+5−3x
−4=5
Step 3: Add 4 to both sides.
−4+4=5+4
0=9
L(which is length) is equal to 42 divided by width which is 6. so the equation is L=42/6
