Best ResponseYou've already chosen the best response.0well from there i got 3+3sqrt2= 6sqrt2 + sqrt85

Kathatesmath94

Best ResponseYou've already chosen the best response.0Part 1: Find the perimeter of a rectangular object which has a length of sqrt 128 feet and a width of sqrt 200 feet. Part 2: Explain, in complete sentences, how you arrived at the answer and give the final solution in simplified radical form. Part 3: What type of object in your home or school might this be? i am not going to lie I don't even know where to start....

Best ResponseYou've already chosen the best response.0after you multiply?

scarydoor

Best ResponseYou've already chosen the best response.1dw:1354248126981:dw Perimeter = Sum of all sides P = s1 + s2 + s3 + s4 P = 8*sqrt(2) + 10*sqrt(2) + 8*sqrt(2) + 10*sqrt(2) P = 36*sqrt(2)

jim_thompson5910

Best ResponseYou've already chosen the best response.1So the perimeter is \[\Large 36\sqrt{2}\]

Kathatesmath94
 2 years ago
Best ResponseYou've already chosen the best response.0oh so I was suppose to add them not multiply

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.1yes, or you can add the length and width and multiply by 2 this is because P = L + W + L + W P = 2L + 2W P = 2*(L + W)

Kathatesmath94

Best ResponseYou've already chosen the best response.0oh ok that what i was thinking of

jim_thompson5910

Best ResponseYou've already chosen the best response.1Explain, in complete sentences, how you arrived at the answer and give the final solution in simplified radical form you essentially simplify both sqrt(128) and sqrt(200) to get 8*sqrt(2) and 10*sqrt(2) you can either add up the four sides or you can add up the length and width and multiply by 2 either way, you get the answer of \[\Large 36\sqrt{2}\]

Best ResponseYou've already chosen the best response.1What type of object in your home or school might this be? \[\Large 36\sqrt{2} \approx 36(1.41421356)\] \[\Large 36\sqrt{2} \approx 50.91168816\] so the perimeter is roughly 50.91168816 feet

jim_thompson5910

Best ResponseYou've already chosen the best response.1\[\Large 8\sqrt{2} \approx 8(1.41421356)\] \[\Large 8\sqrt{2} \approx 11.31370848\] the width is roughly 11.31370848 feet

Best ResponseYou've already chosen the best response.1\[\Large 10\sqrt{2} \approx 10(1.41421356)\] \[\Large 10\sqrt{2} \approx 14.1421356\] the length is roughly 14.1421356 feet

jim_thompson5910

Best ResponseYou've already chosen the best response.1so you just have to name an object that's roughly 14.1421356 ft by 11.31370848 ft

Kathatesmath94

Best ResponseYou've already chosen the best response.0so it could be a pool right? for the object?

jim_thompson5910

Best ResponseYou've already chosen the best response.0Part 1: Find the area of a rectangular object which has a length of 4sqrt2 inches and a width of 6sqrt6 inches. Part 2: Explain, in complete sentences, how you arrived at the simplified answer and give the final solution in simplified radical form. Part 3: What type of object in your home or school might this be? dw:1354248883689:dw

jim_thompson5910

Best ResponseYou've already chosen the best response.1ok it's a bit different because they want the area this time

jim_thompson5910

Best ResponseYou've already chosen the best response.0ok so first i have to simplify the sqrts 6sqrt 6 = 6+3sqrt2?

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.1how are you getting 6sqrt 6 = 6+3sqrt2

Kathatesmath94
 2 years ago
Best ResponseYou've already chosen the best response.0uhhh i might of factored wrong because i took the factors 2 and 3 and pulled the 3 out to add to the 6 and left the 2 inside the radical

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.1you can't do that

jim_thompson5910

Best ResponseYou've already chosen the best response.16*sqrt(6) is as simple as it gets

Kathatesmath94

Best ResponseYou've already chosen the best response.0i was trying to make it so both of my radicals have the same square root thing of sqrt2

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.1notice that 6 has no factors that are perfect squares (ignore 1)

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.1so sqrt(6) can't be simplified

Kathatesmath94
 2 years ago
Best ResponseYou've already chosen the best response.0oh..... i was wondering how that worked cause nothing times itself equals 6

jim_thompson5910

Best ResponseYou've already chosen the best response.0what is ur question, i mean what r u trying to find exactly?

Ammarah

Best ResponseYou've already chosen the best response.0so u multiply and then plugg it back in to the equation.

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.1so 6*sqrt(6) times 4*sqrt(2) = 24*sqrt(12) simplify 24*sqrt(12)

Ammarah

Best ResponseYou've already chosen the best response.0sorry idk why that post just showed up i have a major delay

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.1yes since you can't simplify the length/width just multiply them out

Kathatesmath94

Best ResponseYou've already chosen the best response.0now is 24sqrt12 the radical area that needs to be converted into the approximate length?

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.1simplify that 24*sqrt(12) 24*sqrt(4*3) 24*sqrt(4)*sqrt(3) 24*2*sqrt(3) 48*sqrt(3)

Kathatesmath94

Best ResponseYou've already chosen the best response.0and do you get the approximate length by putting the number in the calculator? i meant to ask you how you did that last time

jim_thompson5910
 2 years ago
Best ResponseYou've already chosen the best response.1so the area is 48*sqrt(3) square inches

jim_thompson5910
