I’m going to use the second one to explain
-8j + 14 = -2(4j-7)
So you distribute -2 into the parentheses on the right side, and you get -8j + 14, which is the same as the left side. Therefore, it is a true statement. It turns from a - to a + because it is two negative numbers multiplying by each other.
Angles in a triangle total 180°
180=128+5x+10+9x
180-128-10=5x+9x
42=14x
x=3
Answer:
1 torr is equal to 133.322368 pascals
A central angle : π / 6 = 30 °
30 ° = 360 ° / 12
The area of the sector is 1/12 of the area of a circle.
Therefore area of the sector is:
A = 36 π / 12 = 3 π
Answer: A ) 3 π in²
Step-by-step explanation:
f(x) =2x - 5
f(k-2) = 2(k-2) - 5
= 2k -4-5
= 2k - 9
