Answer:
7 sorry if I’m wrong
Step-by-step explanation:
X^2 + 30x + 21
= ( x + 15)^2 - 225 + 21
= (x + 15)^2 - 204
Its D minimum at -204
Answer:
x = 3, x = 15, x = 12, x = 1
Hope this helps :)
Step-by-step explanation:
1.) 4x - 1 = 2x + 5
+1 +1
4x = 2x + 6
-2x -2x
2x = 6
x = 3
2.) 3x - 5 = 2x + 10
+5 +5
3x = 2x + 15
-2x -2x
x = 15
3.) 4x + 2 + 30 = 8 + 6x
4x + 32 = 8 + 6x
-8 -8
4x + 24 = 6x
-4x -4x
24 = 2x
x = 12
4.) 4( x - 1) + 5 = 2x + 3
4x -4 + 5 = 2x + 3
4x + 1 = 2x + 3
-1 -1
4x = 2x + 2
-2x -2x
2x = 2
x = 1
