Answer:
b⁴ + 16b³ + 28b² - 242b + 780
Step-by-step explanation:
(b+10) (b³+6b²-32b+78)
b⁴ + 6b³ + 10b³ - 32b² + 60b² + 78b - 320b + 780
= b⁴ + 16b³ + 28b² - 242b + 780

Step-by-step explanation:
Answer: (0, -3)
Step-by-step explanation:
Add both equations to eliminate x
6x-4y=12
+ -6x+y=-3
-----------------
-3y = 9
y = -3
Substitute y=-3 into the second equation:
-6x=(-3)=-3
-6x=0
x = 0
Therefore, the ordered pair of solutions is (0, -3)
Answer:
x = 0
Step-by-step explanation:
x + 1 = x/5
5(x + 1) = 5
5x + 5 = 5
5x = 5 - 5
5x = 0
x = 0
