(90x^22y^17−108x^17y^11+90x^16y^4)/−9x^5y^2
my answer is : -(2x^11y^2)(5x^6y^13-6xy^7+5) but it says it can be simplified

Amazing how the robot tutor cannot do simple arithmetic and consistently gives wrong answers. (0.05m/15.05m) / (41-20) = .003322/21 , not .0012/21 = .000158 , not .000062
I think the robot tutor messes this one up too! I am not overly familiar with physics or chemistry, so I looked up "Ideal Gas Law" and found a Khan Academy video in which Mr. Khan explained it in his usual down-to-earth way. so according to the above, we
Nope, the robot tutor messes up another simple math problem correct solution: ar = 6 and ar^3= 54 therefore r^2 = 9 ----> r = ± 3 if r = 3, a = 2 and sum(5) = 2( 3^5 - 1)/(3-1) = 242 if r = -3, a = -2 and sum(5) = -2( (-3)^5 - 1)/(-3-1) = -2(-244)/-4 =
Ahh, so close! The robot tutor got the slope part right, but got bogged down with simple arithmetic y = (-15)x + b sub in (10,-1) -1 = (-1/5)(10) + b -1 = -2 + b b = 1 your equation is y = (-1/5)x + 1
I disagree with the answer given by the robot tutor. since you want to represent 13/8 , you would need 2 circles, each one divided into 8 equal parts. One circle won't do it.
Nope, the robot tutor is wrong again trying to do math question
Nope, the robot tutor is wrong again!
Absurd question followed by an absurd answer by the robot tutor
Uchenna, that is because the answers on this webpage are now produced by some kind of robot tutor (AI). It just states an answer without any explanation or solution. But most of the more complicated questions in math are wrong. Here is how I would do your
response of the robot tutor: Blake's mistake: 4 • (5 • m) Correct answer: 4 • 5 • m I think the AI is confused. As AL would sing as he regressed: "Daisy, Daisy, give me your answer do ....."
Question cannot be answered because of lack of data
note to robot tutor: in standard math notation we would write this as 3(4a + 6b - 2c)
.... = 2a + ay + 2b + by
Julia's solution was not show, so how can we correct it ? the robot tutor somehow saw a mistake in 3(x+2) = 3x + 6 and the "corrected" it by stating exactly the same result, lol btw, if the robot's clairvoyance property was able to see Julia's solution,
Not possible to answer because of missing data, amazing how the robot tutor (AI) is clairvoyant and can see the segments.
OH NO! The robot tutor messed this one up. You need the slant height, not the perpendicular height to find SA SA of cone = π r l = π(5)(13) , did you recognize the 5-12-13 right-angled triangle? = appr 204.2 cm^2 I did not include the surface area of the
Impressive reply by the robot tutor. It got the analysis of the problem correct, even though it made an error in basic arithmetic for the area of the curved cylinder ( 2(22/7)(3.5)(20) = 440 , not 420 ) , but that can be overlooked. but .... who in 2022
Impossible to answer the question because of lack of data Answer by the robot tutor makes no sense.

Never seen that formula stated by the robot tutor for an Annuity Due. In such an annuity, the payments are made at the beginning of the period, so the simplest way is to annualize your problem and adjust the common formula for a standard annuity, where the
nope, the stated answers don't even satisfy the required conditions.

Curious how the AI robot tutor got its wrong answer this time. real solution: amount spent per day = $5 + $2 = $7 so for 1 week = 5(7) = $35 so in 4 weeks = 4(35) = $140
Isn't it amazing how the robot tutor can see tables and diagrams missing from the posted question. The question just can't be answered, period!

Nope!! linear expression = 2(x+4) + 2(2x-2) = 6x + 4 so when x = 7, perimeter = 42 + 4 = 46 , not 48 !!
Question can't be answered since data is missing angle B --- x angle A --- 2x angle C ---- 180 - 3x
WRONG AGAIN! (-3,-2) --- left 1 unit ----> (-4,-2) (-4,-2) --- reflect over y-axis ---> (4, -2)
mmmhhh? C(3) = 15.3(3) + 20.7 = $ 66.60
The robot tutor actually started off quite well, but then messed up after d days, Jane will have 4d + 50 , (the robot had that) after d days, Ellis will have 6d + 24 , the robot had that too how long before the have the same ? 6d + 24 = 4d + 50 , the robot
Again, don't trust the robot tutor, it is wrong once again ! let the time taken for the faster train to overtake the slower train be t hrs distance covered by slow train = 30t distance covered by the faster train = 55t 55t - 30t = 300 25t = 300 t = 12 in
The robot tutor didn't even answer the question that was asked. total time needed to drive = 1620 km/60 km/h = 27 hours but he wants to drive only 8 hours per days, so 27/8 or 3.375 of 8 hour stretches. So he will need 3 whole days plus another 3 hours on
by definition of the square root symbol √4 = 2 but x^2 = 4 gives us x = ± 2 Even Google and calculators of all types have been programmed to give √4 = 2
Unfortunately the solutions given by the robot tutor are wrong once more. I subbed them in and both of them don't yield a zero. correct solution: 2x^2 - 7x - 4 = 0 (x - 4)(2x + 1) = 0 so x = 4 or x = -1/2
Oh my goodness, the robot tutor messed up even a simple multiplication .... ! 802.95(1.0975) = 881.24
How could the robot tutor miss something so obvious ?? the additive inverse of 5/-12 is 5/12 the robot should know that 5/-12 is the same as -5/12
The robot tutor is wrong again. f(x) = 6x^2 - 12x + k f ' (x) = 12x - 12 = 0 for a max/min 12x - 12 = 0 x = 1 since our parabola opens upwards we will have a minimum at x = 1 that min = f(1) = 6(1)^2 - 12(1) + k = -6 + k
Again, the robot tutor just blurted out an answer without any solution, explanation or clarification. This serves the students absolutely no purpose, especially if that answer once again is incorrect. (in the good old days, when humans were monitoring the
A 5th grader could get the correct answer for this easy problem however our robot tutor missed it. sister's age --- x Anna's age --- x+8 x + x + 8 = 32 2x = 24 x = 12 So Anna is 20 and her sister is 12 check: is the sum of their ages 32 ? YES is Anna 8
This question is clearly too complicated for the robot tutor to finish Assuming the units are in degrees: c + c+20 + 2(c+20) = 180 c + c + 20 + 2c + 40 = 180 4c = 120 c = 30 angle C = 30°, angle B = 50° and angle A = 100°
Another wrong answer by the robot tutor for a trivial math problem (x + 5) + (-4x - 2) + (2x -1) = -x + 2
see my reply to the previous question
This is absurd. No "figures" or diagrams can be shown on this website yet the robot tutor gives an actual answer, which is not possible for the question that was asked.
