Answer: side 1 = 4m, side 2 = 4m, side 3 = 3m
2 times 4 = 8
8 - 5 = 3
Perimeter of triangle = 4 + 4 + 3
P = 11 m
As the given equation is a quadratic equation, the domain is all real numbers. There is actually no limitation to a quadratic equation, because these equations can spread and are indefinitely continuous. Therefore, it makes no sense to have a limiter by a limited domain set.
Answer: No solution
Step-by-step explanation:
Once you simplify the problem, you end up with -10=0 which is false.
Answer: the price of each CD before tax is $14.9
Step-by-step explanation:
Let x represent the price of each CD before tax.
Abdul bought 3 CDs that were each the same price. It means that the total cost of the 3 CDs before tax is $3x.
Including sales tax, he paid a total of $47.40. Of that total, $2.70 was tax. It means that
3x + 2.7 = 47.4
3x = 47.4 - 2.7
3x = 44.7
x = 44.7/3
x = 14.9
the price of each CD before tax is $14.9
Answer:
Your first step should be to separate the x's and the numbers.
This is how I would do it:
-3x+2-5x-7=4x+2
-3x-5x-4x=2-2+7
-12x=7
x=-7/12
