"lateral, of, at, toward, or from the side or sides."
The lateral side of a triangular prism would be a rectangle, like in this picture.
The picture shows two quadrilateral triangles as the faces of the prism, and three rectangles as the lateral sides.
Answer: parallelograms.
Step-by-step explanation:
The lesson states that the lateral faces of a prism are parallelograms.
B. P(A) • P(B)
C. P(A) + P(B)
D. P(A x B)
Answers
Answer: The correct option is (B) P(A) • P(B).
Step-by-step explanation: Given that the probability for success of an event is P(A) and the probability of success of a second event is P(B).
We are to find the probability of both events occurring, in that order.
We know that
if two events are independent of each other, then the probability of the intersection of the two events is given by the product of the probabilities of the events.
Here, the event that both events occur is given by (A ∩ B).
And, so the probability of both events occurring, in that order will be
Thus, the required probability is P(A) • P(B).
Option (B) is CORRECT.
To work out the success of both events you have to multiply them together. I'd seriously reccomend learning this rule as it's very important later on in mathematics as it's basically the foundation of all probability statistics.

but we're going to find out.
-- We're told that the length is 4 times as much. So the length is ' 4 W '.
-- Perimeter is (2 widths) + (2 lengths).
2 widths = 2 W
2 lengths = 8 W
Perimeter = 10 W
-- We're also told that the perimeter is 55m. That's just what we need.
10 W = 55 m
Divide each side of this equation by 10:
W = 5.5 m
There's the width !
The length of the hall is 4 times as much.
Length = 4 W = 22 m

(x + 12) = 4x – 1
Answers
First, if we want to solve it, we would take our equation, (i like decimals) .5(x+12)=4x-1 and distribute the .5 to both things in the parentheses. when we do that we get .5x+6=4x-1. now we get our variables to the same side by subtracting .5x from both sides. When we do this, we are left with 6=3.5x-1. next we add 1 to each side and get 7=3.5x. Now we divide each side by 3.5, and get x=2. Now we have to plug it into the original equation and get .5(2+12)=4(2)-1. when we simplify this we get .5(14)=7, which goes to 7=7. this is a true statement, so we know that x=2. since we only have one value for x, we know the answer is that only one solution exists.
Another way that is simpler, but not always accurate, is to look at the variable. There can only be as many solutions for x as the highest exponent x is to, in this case, x has no exponent so there can't be more than one solution, so we say that it has one solution. This way is a lot faster, but can be wrong if the equation has a false solution. This false solution happens when you solve the equation and get a value, but it doesn't work for the original equation.
The second way is a lot faster, but the first way will always give you the right answer

1/2 of 4 = 4/2
4/2 simplifies to 2/1
2/1 is 2
2
Now multiply 2/4 * 4/1 = 8/4
8/4 can be reduced by 4
8/4 = 2
4/4=1
So u have 2/1 = 2
