2x + 3y = 1470
Minus 2x from both sides gives
3y = 1470 - 2x
divide through by 3
y = 490 - 2/3x
4n^4 √3n I believe would be the simplified form.
After a first glance you can see that 3x^2 - 75 is not a difference of squares in the current form, because for one 3 and 75 are not squares.
So we'll have to see if we can factor something out of both of them. The only number it can be is 3, because the only number besides 3 that goes into 3 is 1.
So is there any number that can multiply by 3 to equal 75?
If you said 25 then you are correct. :p
So then our problem would look like this:
3(x^2 - 25)
Now we have a difference of squares!
Remember a difference of squares can be factored like this!
(a^2 - b^2) = (a - b)(a + b)
3(x - 5)(x + 5)
Is our answer!
I don't understand what you mean
Since point M is the midpoint of LN, LM and MN are equivalent in length.
7x - 12 = 3x + 16 (LM=MN)
7x = 3x + 28
4x = 28
x = 7
Now that we know the value of x, we can find the value of LM by plugging the value in the equation.
LM = 7(7) - 12
LM = 49 - 12
LM = 37
