Not sure the question but the only one that makes since is Line 1....
3*x^2 =6x^2
3*2x=6x
and the -7 its just in a different form
3(3+5)=6+15 1)3x3 2)3x5 then you up the answers that you get for one and two
We can get two different equations from this:
3x = 18
and
3x = -18
So:
x = 6, x = -6
x = {6, -6}
Check the picture below, notice those three quadrilaterals.
the square, is really a rectangle and is also a rhombus, but with right-angles and equal sides.
Answer:
140m
Step-by-step explanation:
3/4 = .75
x/.7 = 150/.75
multiply both sides by .7
x = 150/.75 * .7
x = 140m
