I can give you an example:
4x^2+2xy-3y^2
it is in the form of :
x^2+2ax+a^2
also : (x+a)^2 = x^2+2ax+a^2
Answer:
The third is if the alternate exterior angles, the angles that are on opposite sides of the transversal and outside the parallel lines, are equal, then the lines are parallel. And, fourth is to see if either the same side interior or same side exterior angles are supplementary or add up to 180 degrees. :)

Answer:
AN = 9
Step-by-step explanation:
so we can imagine this in a line like:
A---------------N---------------X
Step 1 : solve for x
AX=21 (our total)
because we know that AN+NX together makes AX, we put that into an equation
<u>AN + NX = AX </u>
(2x+1) + (3x) = 21
2x + 1 + 3x = 21 <-- <em>subtract 1 from both sides</em>
2x + 3x = 20 <-- <em>add 2x +3x </em>
5x = 20 <-- <em>divide 5 from both sides</em>
<u>x = 4</u>
Step 2 : input x into AN
AN = 2x + 1 <-- <em>input 4 for x</em>
AN = 2(4) + 1 <-- <em>simplify from there</em>
<u><em>AN = 9</em></u>

Answer:
74
Step-by-step explanation:
The cube root of 74^3 will be 74. The cub and cube root cancel each other out.
