NOTES: Find the common factor of the terms and factor it out:
1. Answer: 15r²(3r - 1)
<u>Step-by-step explanation:</u>
45r³ - 15r² <em>they both have 15 and r² as factors</em>
= 15r²(3r - 1)
************************************************************************************
2. Answer: 3x(3x - 1)
<u>Step-by-step explanation:</u>
9x² - 3x <em>they both have 13 and x as factors</em>
= 3x (3x - 1)
************************************************************************************
3. Answer: x(x + 3)
<u>Step-by-step explanation:</u>
x² + 3x <em>they both have x as a factor</em>
= x(x + 3)
Answer: 7°
Explanation:
FBD = EBC
2x + 3 = 9x - 11
-7x = -14
x = -14/-7
x = 2
EBC = 9(2) - 11 = 18 - 11 = 7°
Answer:
18b-3c-10
Step-by-step explanation:
16b+5c-10-8c+2b
<h3>Combine like terms [ 16b+2b=18b] [5c-8c=-3c] [and then -10 is alone bc its doesnt have any friends to combine with.]</h3>
Answer:
Coordinates of P are (-3/2, 2).
Step-by-step explanation:
At the point oif intersection:
2x + 5 = 2
2x = -3
x = -3/2.
This doesn’t make any sense
