Answer:
k = -2
Step-by-step explanation:
The determinant can be formed by subtracting up-diagonal products from down-diagonal products:
(x)(x+y)(y) +(y)(x)(x+y) +(x+y)(y)(x) -(x+y)^3 -x^3 -y^3
= 3xy(x+y) -(x^3 +3x^2y +3xy^2 +y^3) -x^3 -y^3
= -2(x^3 +y^3)
The value of k is -2.
Sent a pic of the solution (s). When it asked to factor out the coefficient of the variable just divide both numbers by the coefficient, and present it on the outside like I showed you.
Question: The area of triangle MNP is how many times the area of triangle JKL?
Answer: The answer you want would be 9... The area of triangle MNP is 9 times larger than the area of triangle JKL.
Explanation: It would be 9 times larger because it says the base and height which means multiply the base and the height so it would be 3*3=9
Hope It Helps!!
M=38 I hope it helps
Can u give me the brainliest ^^ plz ☺️☺️
Answer:
Total 25.45 hours will be taken to empty the pool.
Step-by-step explanation:
Time taken by large pumpkin to empty the pool=40 hours
Time taken by the smaller pumpkins to empty the pool=70 hours
Amount of pool emptied by large pumpkin in one hour=
Amount of pool emptied by small pumpkin in one hour=
Amount of pool emptied in one hour if both pumpkins work together=
+ 
=
Therefore, the no. of days will be the reciprocal of the amount of work done in one hour ie . 
Total 25.45 hours will be taken to empty the pool.
