2(m-n^2)-6(n^2+3m)
=2m-2n^2-6n^2+18m
=20m-8n^2
Done ✅ Hope it helps
Answer:
B
Step-by-step explanation:
x² - 4x - 7 = 0
(x - 2)² = 11
Answer:
1.) The point (24,30) would not be on the line
2.) The point (12,13) would not be on the line either
4.) The slope is a fraction of 2/1
Bonus: y = (2/1)x - 2
Step-by-step explanation:
For question three, I looked at the (6,10) point on the graph and compared it with the (a,8) point. That showed me that the y coordinate always moves by 2. Then I looked at the (6,10) coordinate and the (a,8) coordinate and the (4,b) coordinate and saw that there was one x coordinate between 6 and 4 so it must be five. That means the x coordinate moves by 1.
Let me know if you need more help!

Answer:
-13
Step-by-step explanation:
I didn't incliDE the 3 at the first if I need to include it I will do again
Sometimes it helps to draw it...so u can see
7 7
J_______K_________L

4x - 2
since K is the midpoint, it splits the segment in 2 equal parts
JK + KL = JL
7 + 7 = 4x - 2
14 = 4x - 2
14 + 2 = 4x
16 = 4x
16/4 = x
4 = x <====
KL = 7 <===
JL = 4x - 2....4(4) - 2.....16 - 2 = 14 <==
