Its the first one because -3(-2)=6, 1(-2)=-2, 2(-2)=4 are all correct
Answer:
Volume = 100 
Step-by-step explanation:
Volume, V= Bh
length = 10 inches
width = 5 inches
height = 2 inches
So that,
B = 5(10)
= 50 
B = 50 
Then,
V = (50)(2)
= 100
v = 100 
Answer:
The distance between x and y on the number line is 2x
Step-by-step explanation:
we know that
If y is the opposite of x
then

The distance between x and y is equal to


Answer:
Step-by-step explanation:
Comment
You are given values for the adjacent side of <x and the hypotenuse of a right triangle. This defines the Cosine of an angle
Equation
Cos(x) = a/c the way you have labeled it.
Givens
a = 9
c = 18
Solution
Cos(x) = a / c
Cos(x) = 9 / 18
cos(x) = 1/2
x = cos-1(1/2)
x = 60 degrees
Answer
x = 60
