The first part of the second line, she left the -5 there. The correct work and solution should be this:
5(2x-1)-3x=5x+9
<span><span>7x</span>−5</span>=<span><span>5x</span>+<span>9
</span></span>2x-5=9
2x=14
x=7
Answer:
(2p+7)(3p²+4p-3)
2p(3p²+4p-3)+7(3p²+4p+3)
(6p³+8p²-6p)+ (21p²+28p+21)
6p³+29p²-6p+21
7 or 8 since 2 and a half hours isnt an even amount of time so thered be an extra 10 minutes
When you have two parallel lines being cut by a transversal, you can use the next statements for the angles:
The measurement of the angles in green is the same (are congruents)
The measurement of the angles in blue is the same (are congruents)
An angle in green is a complementary angle with an angle in blue. (The addition of the two angles has to be 180º)
You know that:

As the angle 3 is congruent with angle 2:
