A) L = (2*W) -4
B) L*W = 160
B) L = 160/W
Substituting that into A)
160/W = (2*W) -4
160 = 2W^2 -4W
2W^2 -4W-160 = 0
Width = 10
Length = 16

Help pls!!! The radius of a circle is 15 inches. Enter the area of the circle, in square inches. Round your answer to the neares
Bas_tet [7]

Answer:

706.5 inches squared

Step-by-step explanation:

The formula for the area of a circle is pi r^2. r being the radius. Because you have the radius, and pi is 3.14 in this case, your new formula is A=3.14(15)^2. 15 squared is 225, times 3.14 gives you 706.5

Your final answer is already in tenths so you don't need to round! Hope this helps :)) and brainliest is always appreciated

Replace * with a monomial in such a way, that the trinomial becomes a perfect square. *+12x+1
Mrrafil [7]

Answer: * = 36x^2

Note: Im guessing you're here for rsm struggles. That's how I found this question. I searched the web for the answer to this rsm problem, but I couldnt find it. I was happy to find this brainly link, but annoyed to find it was unanswered. I did the problem, and now i'll help future rsm strugglers out. Thanks for posting this question.

Step-by-step explanation:

Ok, so we know that trinomials like this are squares of binomials. this in mind, we know that it can also be written as (x+y)^2. (also brainly's exponents feature used to be better, if the exponents are confusing you, comment.) Using the (x+y)^2 equation, you know that by simplifying it, you get x^2+2xy+y^2. Basically we're looking for x^2. Using the middle term, 2xy, or 12x in this equation, we can find x. since we know the square root of 1 is 1, we know 12=2x. This is kinda confusing, but basically since the answer is 6, we know that the x-term is 6x. We square 6x and get 36x^2. guaranteed to work on the rsm student portal, i'm in rsm and i just answered this question.

Hope this helps! Also, im not usually too active on brainly unless im looking for HW answers, so if you understand this explanation and you see a confused comment, help out a friend and answer it. Happy holidays!
