Answer:
the gas constant of each gas
Step-by-step explanation:
m before the angle symbol stands for angle
angle acb = 180 - 108 = 72 degrees
180 = a+b+ angle acb
180 = a + 32 +72
180 = a + 110
A = 70
Answer:
y = -3
Step-by-step explanation:
1.5y + 3 = -1.5
When doing algebraic equations, you are always doing PEMDAS backwards.
First, subtract:
1.5y = -4.5
Then divide:
y = -3
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
