Thank you so much!!
Thank you!!
In part B, how did you split the bottom x-4 into (x+2)(x-2) I thought you could only do that if it was (x-4)^2?
Thank you so much! I believe on our test it'll be specified that we need to use the quotient method, just to check if we know it..but if it isn't I will use that trick! Thanks! I like the power rule better too.
Uh I meant a point on the graph. Answer is (2,-8).. I figured it out. but thank you, I do need to graph it later on.
Thank you!
Thank you! I'm not allowed to use a calculator to graph on the test and I don't really understand the graph aspect of this yet...but this is what I needed to show on the problem, so thanks! I will definitely be looking into the graphing though, as that is something I really struggle with.
Thank you! I understand now :)
The area of a square = (s^2). All sides are equal.
You need to work backwards since they give you area = 25m squared.
Square root the area to get rid of the square.
sqrt(25)= 5
The length of the edging = 5m
7/10 is bigger.
To reach this answer you take a common denominator by multiplying the given denominators with the opposite numerators.
7(14)= 98 9(10)=90
Thus 98 > 90.
6x-6+10x+6+28 = 16x + 28
(729/9)/54 = 81/54 = 3/2 [This is wrong, see CPhill's answer for correct answer.]
