Why is (x^2+2xy+y^2) greater than 2(x+y) when x and y are over zero and X>Y

Mathematics
1 answer:
VikaD [51]3 years ago

Answer:

Step-by-step explanation:

This is true because if we were to plug in values for x and y the first equation will have a greater value.

Lets try 2 for x and y......

2^2+2(2)(2)+2^2                                                                                              

4+8+4

=16

and for the other expression

2(2+2)

4+4

8

And 16 is greater then 8 this is true for all real rational numbers

Answer: With the equation being negative you would multiply it to most likely get a positive if Z is Negative. If Z is a positive but also a higher number the equation is defenitly positive. I dont know the exact answer do to the fact that you didint show the whole question.

Jade says that 8÷ 1/2 means the same thing as 1/2 of 8, so the answer is 4 do you agree
algol13

Answer:

no

Step-by-step explanation:

8÷ 1/2

Copy dot flip

8 * 2/1 = 16

Divide 8 things in half you get 16

1/2 of 8 = 1/2 * 8 = 4

Half of 8 things is 4

They are not the same

What is the value of x​
Oksana_A [137]

Answer:

Split it into two triangles at the 110 degree angles. Each triangle needs to add up to 180 degrees. If there are two triangles, total should be 360 degrees. So the whole figure should have 360 degrees. 110+110+70 = 290 degrees. 360-290 = 70 degrees. 70/5 = 14 degrees.

There is also congruence between the triangles through which we can assume 5x will equal 70 degrees.

The type of figure it is also means the angles will be the same on opposite sides
