Answer:
Step-by-step explanation:
<u><em>b).</em></u>
2x² - 9x - 5 = ( x - 5 )( 2x + 1 )
3x² - 15x = 3x ( x - 5 )

Answer:
$11.49
Step-by-step explanation:
Answer:
Interior Angle Theorem
x=5
measure of angles: 46, 46, 134
Step-by-step explanation:
Interior angle theorem
12x-14=5x+21
7x=35
x=5
12x-14=12(5)-14=46
5x+21=5(5)+21=46
20x+34=20(5)+34=134
To solve this problem you will need to multiply the terms using distributive property
(5+√3)(5-√3)= 25-5√3+5√3-3)=22
choice b
