Answer:
(a-b)^3 = a^3 - 3a^2b + 3ab^2 - b^3.
Step-by-step explanation:
3x+5=4
move the positive number to the right side over the equal sign.
NB.lf the number that u moved over is positive(it as a plus sign before it ) the number will become negative when moved over the equal sign. If the number has a minus sign then when it is moved over the equal sign it becomes positive.
so for this because we have a +5.it will then be
3x=4-5
3x=-1
To get x you divide both side by 3
3x/3=-1/3
therefore x =-1/3
I got 30%
60% as a decimal is 0.6
18% as a decimal is 0.18
0.6 times 30% or 0.3 is 0.18
